No the CPU is a PowerPC, not and Intel x86 unit.
If you want windows on that it'll have to emulate a x86 CPU first in software, and likely run about 1/3 of clock speed -- ie, painfully slow.
There are variant of Linux that you can find.

The Mac Intels conform enough to the PC standard, that they are several drivers away (bootcamp) from natively running x86 software. So full clock speed ahead with Windows.
