Yes, you'll be able to work through the course using Linux without any problems. The only software that's in use is DBeaver and Postgres - both of which run on Linux, Mac, and Windows.
I'll make a note to record a setup video for Linux as well (though in truth, the Mac and Windows setup videos are practically identical anyway owing to the cross-platform software in-use)
I sent a message from the course site, but would probably want to consider installing postgresql via docker, which can be a one-liner in any platform with docker installed (including docker desktop for mac/windows).
