Sure, you can e.g. do

\documentclass{book}
\usepackage{xltxtra}

\usepackage{polyglossia}
\usepackage{arabxetex}
\let\aemph\veryundefinedcommand
\begin{document}test run\end{document}

This will have the effect that the definition of polyglossia (done
at \begin{document}) will win. 

If you want the other definition you can do something like this:

\documentclass{book}
\usepackage{xltxtra}

\usepackage{polyglossia}
\usepackage{arabxetex}

\let\ORIaemph\aemph
\AtEndPreamble{\let\aemph\ORIaemph}
\let\aemph\veryundefinedcommand
\begin{document}
test run
\end{document}
