The location of _region_.tex seems to be pretty much hard-coded.  It's
written by `TeX-region-create' which is called in `preview-region'.  If
you wanted to experiment with that, you could set the `nondirectory'
parameter of `TeX-region-file' in the call to `TeX-region-create' and
provide a directory yourself.

I'm not sure if moving _region_.tex to another directory makes much
sense, though, because compilation of the file will fail if it loads
files from the master directory.  And such a situation is not uncommon.
