No, you can't. The largest DIMMs the 2.2 will take are 2GB ones, and it can't address more than 3GB, so it's already maxed out:

Ah, that sounds familiar now. Thanks! –  chrispix Mar 9 '11 at 20:44

In addition to what Mike Scott said (you're already at the maximum), the RAM from your new Mac is DDR3, while your old Mac uses DDR2, so the sticks probably won't even fit.
