it would be easier if you gave us your macs model number
but if apple says so, probably. there have been a few cases where you could use m ore then apple specified, like the current Mac Pros
If it's the one in your sig, I think it's this model which officially supported only 4GB but actually worked with up to 6GB. There was a later 2.66GHz model that supported 8GB but I think that is a different model than you have.
