I recall seeing some fanless APUs at that size from AMD, so you may be right. I was only thinking Atom because I know there have been Intel Atom based smart phones so it's a known quantity rather than saying some chip that I don't know would be workable in terms of size, heat, or battery life.

Heat management, is via undervolting/underclocking. These new machines have the option to turn down TDP from 5W to 25W. I have one of these, the GPD Win max, and I can use it on passive cooling.
Battery life is really good. At 5W, you can do the math yourself. My Win max runs for 12 hours with coding tasks and Wifi with Power Saver in windows.
