I was able to replicate your problem. I found a solution here: http://www.tug.org/pipermail/xetex/2005-October/002480.html
From the site:
You could possibly hack around this by wrapping your graphic
inclusion in a macro that outputs glyphs at two diagonally opposite
corners of the image; they could be small blank glyphs (e.g.,
\char32), so as not to show on the page, as long as they're real
glyphs in a font so that xdv2pdf "sees" them. I think that would
trick the driver into creating the proper link area.
Here's the command that does the work (again, from the site):
\newsavebox{\ximagebox}
\newlength{\ximageheight}
\newsavebox{\xglyphbox}
\newlength{\xglyphheight}
\newcommand{\xbox}[1]%
{\savebox{\ximagebox}{#1}%
\settoheight{\ximageheight}{\usebox{\ximagebox}}%
\savebox{\xglyphbox}{\char32}%
\settoheight{\xglyphheight}{\usebox{\xglyphbox}}%
\raisebox{\ximageheight}[0pt][0pt]{\raisebox{-\xglyphheight}[0pt][0pt]{%
\makebox[0pt][l]{\usebox{\xglyphbox}}}}%
\usebox{\ximagebox}%
\raisebox{0pt}[0pt][0pt]{\makebox[0pt][r]{\usebox{\xglyphbox}}}}
To be used as
\hyperlink{page.2}{\xbox{\includegraphics[height=14cm, width=14cm]{tiger}}}

This is a workaround for XeLaTeX as pointed out by @user700902:
I however chose to use LuaLaTeX, which didn't require any change of the source code.
