Simple question. Can I swap my current 12-25 to a 12-28 without any adjustment in chain length?

Should be no problem if the existing chain has been fitted to the correct length.
FWIW I swapped an 11-28 for a 12-30 on my Trek and did not need to fit a new chain or fiddle with the B-screw adjustment.0 -

You only added one tooth. The OP is increasing by three. An extra link pair is probably a good idea but you might get away with the existing chain if it was originally on the long side.Faster than a tent.......0
