Can an ar15 223 be changed over a 308 cal.

No such conversion I'm aware of.  If you wan't an AR in .308 you buy a Armalite AR-10.

No.  Mag well is not big enough.  if .308 upper on .223 lower they won't match.  Many reasons why not.  Buy AR10.

At the risk of sounding like a smartazz, isn't the 300 whisper .308 cal?

as well as the 7.62 by 39mm
(sorry I couldn't help myself)

No.  It is the .300 Whisper.  Groove diameter is .308.  The caliber/cartridge designation is .300 Whisper.
