A hack like
hg diff -r.:tip | patch --dry-run --forward
might give a useful approximation in most cases.

A better answer is this: You should never make an update with 
uncommitted changes in the working directory. If you follow that advice 
then you know that the working directory is clean and the update will be 
smooth.
