You can request the computer you want. They will push you towards Chromebook but you can pick a normal Linux machine or a MacBook or even a Windows computer (don't do this).
I used a Windows laptop for some time. It made browser testing in IE significantly simpler and otherwise worked fine for running Chrome + remote access to workstation. It was also the only model offered with a garaged stylus, which I used and tested quite a lot.
I used that laptop to skip over the lousy overheating butterfly MacBook generation. Now I have an M1 Pro MacBook like everyone else.
