The lungs could be in the human half but just be far larger than typical human lungs. If the organs in the lower part of a human torso are in the horse half it would make room for more lung in the human torso. I don’t imagine you want too much room between the nose/mouth and the lungs if you can help it.

Maybe centaurs have like some sort of gill system or whatever that would be for land walking mammals?
