I, too, think that Tim Cook could do the majority of his work on the entry-level M2 MacBook Air. It has more than enough oomph for your typical everyday tasks like communications and document preparation. You know that he has people available for any heavy lifting that may need to be done, such as video production. Anything else, like their ERP system is most likely cloud-based so you'd only need Safari to access it.
I introduced the president of one of the companies I used to work for to Apple and we got him the original MacBook Air. He used the machine for a couple of years and then we upgraded him to an Air with a bit more memory and storage. He ran the second one for many years and was able to do everything he needed to do on it just fine. We even ran Parallels desktop on it with a Windows VM for a couple of Windows-only applications that he needed. He traveled a great deal, so the portability was a key factor for him.
