Not that I know of off the top of my head (though if there is, I'd be
glad to stash that new knowledge away), but you can do a quick check
before invocation:

diff -q file1 file2 >/dev/null && echo same || vimdiff file1 file2

which could be wrapped in an alias/function to simplify the
invocation.

-tim
