Yes. I put my son on a schedule at this age. I started feeding him every 3 hours or earlier during the day. The important thing is to make sure they get most of their calories during the day. I woke him up at a certain time and started a bedtime routine. It took about a week to adjust, but he started sleeping the longer chunks of sleep at night. He did take 1-2 longer 2-3 hour naps, but the large 4-5 hour chunks were at night.
