Postfix header checks are by default not enabled, so do not reject
empty subjects by default, and can't reject messages with a missing
subject. You don't have to reject empty subjects.

Only by somehow using procmail as content_filter, for which it is
probably not well suited. So basically, no...

You can use a Sieve milter, proxy filter, or defer the processing
to delivery, but then you've already accepted the message, and
should not reject it. You can tag it as spam, and have it delivered
to a suitable sub-folder, or just leave the MUA to deal with the tags.
