P and PE cards are exactly the same, but the PE has an ejector handle. P
will fit in M5/M10 (though not gracefully, be careful with the pins) as
long as you prepare "some other method" for removal. Also, you can
hot-swap M20/M40 PICs just like M5/M10s if you arrange for PIC removal 
through "some other method" than pulling out the FPC. Just offline it in 
software first.

I haven't ever tested a PE in an M20 FPC, so I have no idea if that would
work or if the ejector would get in the way.

PB cards for FPC1 are physically the same hardware as P and PE, though the
face place is so different as to be not directly usable. You can unscrew
it and switch it out with a P/PE faceplate though. PB cards for FPC2
however will not work in FPC1's.
