Yes, if you can get an IEEE-488 card for the IBM, and know how to program the port on the 
PET, you should be able to transfer information.  I recommend, however, that you
write the program in machine language for speed considerations.

Another possiblity is to use the "parallel port" on the PET (i.e. that "other"
connector on the back) which can be accessed from BASIC or ml.  I used this to connect
my PET to a Centronics printer (although it was a custom cable...)

I DO remember reading a few years (~ 5) ago about an parallel-to-serial converter
that attached to the IEE-488 port that gave RS-232 I/O through the 488 interface.
Sorry I can't give a reference.
