"No"
You will have to do something like scan across the intersection of the 
bounding boxes with trace() or inside_object() (or the InObj() macro) to 
find out if there is anything left. And then there is the possibility 
that you simply missed it because you didn't scan the bounding area at a 
high enough resolution, and it would be slow, even if patched into 
POV...and you wouldn't be able to detect if an object just touches 
another this way.
