I disagree. The only reason why they changed the name from PowerBook to MacBook was 1) to get “power” out of the name and 2) to get “Mac” in the name.
The name doesn’t allude to Intel at all (it’s not intelbook), it alludes to it being a Macintosh. Also at this point it has major brand recognition since ‘MacBook’ is their most popular Mac product they sell.
