Possibly, but it’s not a good idea if the cabinets are in the kitchen or bathroom where they are likely to get banged around. The last thing you want is for the paint to chip every time you tap it with a saucer. Sanding is the best way to achieve proper adhesion. It also beautifies by removing blemishes in the old surface and making it smoother so the new coat looks better than ever. The more you sand, the better the finished surface will look. It really takes four coats or more, wet sanded between coats to get a flat, smooth finish, and preferably five or six.
