Yes, that sounds usable. However, ideally I think you should plagiarize the test
t/compile4.sh so that we also test the wrapping of the icl compiler when it is
available. You will need to patch the require_tool function in 
t/ax/am-test-lib.sh
to recognize this "new" icl tool for that to work.

You are also missing a changelog and you need to update the scriptversion at the
top of the compile script.

You could also write the case match as

  cl | *[/\\]cl | cl.exe | *[/\\]cl.exe \
  icl | *[/\\]icl | icl.exe | *[/\\]icl.exe )

in order to not duplicate the code.

Since you send this from an intel account, why is it that -c -o isn't supported?

And another question is if icl supports the -showIncludes option from MSVC? Or
does it have a way of its own to output dependencies? You might want to
support a one-pass mode to find dependencies in the lib/depcomp script.
