\def\table{\def\figurename{Table}\figure}
\let\endtable\endfigure
Should put all figures and tables in the same sequence and write Table for table captions.
The list of figures will still say list of figures, if you want to change that add
\renewcommand\listfigurename{List of Figures and Tables}
Here is another approach. What it does is to check at the end of the document the values of the figure
and table
counters, and add to the .aux
file a boolean flag setting depending on whether these values are zero or positive.
Then you have on next run \iffigures
and \iftables
which allow you to act conditionally.
In the code below, perhaps the \global
are not really needed, I didn't check.
See also a variant at bottom which does not use the figure
/table
counters because they might well be reset to zero due to document sectioning (as pointed out by egreg
in a comment).

Here is for a document with figures but no tables:

And if tables are present:

Three compilations needed.
Variant. I don't know to what extent patching \figure
and \table
as here is OK, depends perhaps on float related packages. At the worst I guess doing the patches immediately after \begin{document}
should be enough (at the end of preamble might not be enough if some package does stuff during At Begin Document).

Best Answer
Right before the appendix, I redefine
\addcontentsline
to intercept{figure}
and{table}
calls and excise them, as follows (requiresifthen
package):Here is my MWE (note: I added a body figure and table to demonstrate ability to discern report body from appendix)
ADDENDUM
A version of the redefinition that does not require the
ifthen
package:
