They didn't describe the full specs of their test rigs (that I saw) but a similarly spec'd Macbook Air is going to get better battery life than the equivalent Framework 12 or 13 based on the 10 hours they quoted for the 12. (The 13 gets even less). And saying that the best possible CPU framework offers in a 13 inch format beats the consumer line of Macbooks.. sometimes.. you would really need to like/need Linux. At which point, get the cheapest Macbook Air M4 you can and then just use the money you save to get a decent NUC.
Why would I get Air M4 if I want to use Linux?
There are many different methods through which one can develop against/on Linux. For example, I have a pretty low spec'd Macbook Air and several different test machines at home that I do remote development against. I prefer a low-heat, high battery life, good performing machine like the Air over a power hungry, loud, and constantly overheating workstation. But, those are my preferences -- some people want to have a single interface through which they do all their work, and the most powerful Linux laptop money can buy. If that's the case, Framework is great!
