Actually, you can.  I just wouldn't suggest doing both at the same time.
 MySQL has binary upgrade scripts, and I've used them to go from 5.0 to
5.1 and 5.1 to 5.5.  (That last upgrade was in error, and I ended up
backing up to 5.1 - fortunately I made copies all along the way.)  You
just have to keep the 2 upgrades separate, and handle only one at a time.
