I believe it could be theoretically done, but I doubt it would be economically viable. Consumer grade electronics is produced with much lower quality standards and designed for much lower physical endurance than aerospace or military electronics. So while they may come with plenty of compute power, they may not withstand harsh conditions in space and you possibly don't want to risk losing a multi-million dollar rocket due to a fault in a $2 doorbell controller.
