LuaTeX has limited support for microtypograhpy now, and it can be invoked if only type1 fonts are used. But is it possible for microtype to work with opentype fonts loaded with fontspec now? I have searched the Internet for this, but most of the relevant information is outdated.
[Tex/LaTex] Is it possible now to use microtype with opentype fonts

This is due to a bug (or, if one were more polite: incompatibility) in luatex. I've just reported it on the luatex list.
Edit: ... and I got an answer, persuading me to be more polite, indeed - it's not a bug but microtype's using a legacy command.
The simple solution is: load the fonts with Renderer=Basic (side effects are yet to be discovered).
Let me add to the confusion a bit:
there are actually two formats for running Plain with LuaTeX!
One of them is the format that gets called when you run the command
luatex from e.g. TeX Live;
egreg already posted instructions for it in
his answer.
There exists, however, another format called luatex-plain. Since it comes with the font loader built in, it has the advantage of being able to use OpenType fonts without additional packages. Here’s a demo (you’ll need the free Minion Pro fonts from Adobe for the second part):
\font\iwonaregular =file:Iwona-Regular at 12pt
\font\iwonaitalic =file:Iwona-Italic at 12pt
\font\iwonabold =file:Iwona-Bold at 12pt
\font\iwonabolditalic=file:Iwona-BoldItalic at 12pt
{\iwonaregular foo}\par
{\iwonaitalic bar}\par
{\iwonabold baz}\par
{\iwonabolditalic xyzzy}\par
\font\minionproliningfigures =file:MinionPro_Regular at 12pt
\font\minionprotextfigures =file:MinionPro_Regular:+onum; at 12pt
\font\minionprosmallcaps =file:MinionPro_Regular:+smcp; at 12pt
{\minionproliningfigures 0123456789abcdef}\par
{\minionprotextfigures 0123456789abcdef}\par
{\minionprosmallcaps 0123456789abcdef}\par %% implicit +onum!
\bye
For more complicated examples see the test file.
luatex-plain is distributed with ConTeXt and available through TeX
Live in the directory texmf-dist/tex/generic/context/luatex/.
(Pro Tip: build the format and then symlink the luatex binary
to luatex-plain, so you don’t have to specify the --fmt
parameter.)

You ask whether
The short answer is yes. A longer answer would add that
microtype's functionality under LuaLaTeX isn't as complete as it is under pdfLaTeX. However, the limitations are not caused by the use of OpenType fonts.The version of
microtypethat's currently distributed with TeXLive 2012 and MikTeX 2.9 is still version 2.4. However, a late-beta edition of version 2.5 of themicrotypepackage, dated 2012-05-23, may be downloaded from http://tlcontrib.metatex.org/cgi-bin/package.cgi/action=view/id=608. This version, when run under LuaLaTeX, still isn't as capable as when it's run under pdfLaTeX, but it comes a lot closer than if you stick with version 2.4.You ask in a follow-up comment how version 2.5 of
microtypemight be installed manually under MikTeX. Do you have a "local" directory set up among the directories that are searched by MikTeX? (Bring up the "Settings" app of MikTeX to find out.) If not, do set up such a directory. Then, you couldmake sure that this local directory is topmost in the search order (so that the version of
microtypeto be installed by you in the local directory are seen before the "official" but now somewhat obsolete version that's still distributed with MikTeX 2.9);copy the files of microtype 2.5 beta to subdirectories of the local directory (such as
..\tex\latex\microtypeand..\doc\microtype); andupdate MikTeX's filename database; the particulars of this update process will depend on whether or not you installed MikTeX in ordinary mode or admin mode.
Update: Version 2.5a of the
microtypepackage was released in May 2013.
