I like Chromebooks, but I haven't installed J there yet. Two thoughts come to mind.
First, many / most CBs support Android apps, so perhaps you can install the Android version. Second, you can also run "Linux apps" (I think they mean packages) on ChromeOS. See https://www.computerworld.com/article/3314739/how-to-use-linux-apps-on-chrome-os.html. The only thing that seems missing in that description is installing a package that's not part of a standard repo, but that doesn't mean it's impossible. I like the sound of these approaches better than enabling developer mode: as I understand it, enabling developer mode shuts off some of the security features ChromeOS is known for.
