Yes I would say so, easily at least for the intended purposes. My old 2017 MBP 15" would spin fans quite often, and was basically always hot. When I used it in clamshell mode connected to a TB dock it would always make noise AND be quite warm, hot even depending on the workload and ambient temps.
My M1 Air? It's cool to the touch. I've had it become warm-ish on a few occasions, mainly in clamshell mode. But it is usually surprisingly cool when I disconnect it to put it in my backpack after a full day at the office in clamshell mode. I can't really convey how nice it is to have a quiet computer, that still stays cold almost like an Ipad. It's wonderful!
