Is it possible to exchange my MacBook Air M2 for MacBook Pro M3?

I believe that if you buy a Mac directly from Apple, you have 14 days to return it. So you could do an "exchange" by doing a return, followed by a new purchase. In your case, two months have elapsed, so if you bought it from Apple, I don't think you would have this option any more. (Just a guess. I don't work or speak for Apple.)

If you bought the Mac from some other retailer, check their return/exchange policies.

The Apple return/exchange period is 14 days. See: Returns & Refunds - Shopping Help - Apple

If you purchased from an Apple Reseller, they may have a different policy.
