If ChromeOS is supported, you should be fine. ChromeOS is basically Gentoo with Chrome as the UI for everything. This looks more like a “this is what we tested this site on” than “you absolutely need those specs to do what you have to do”.
I just used government sites that recommend Internet Explorer 11 just fine on Firefox. Maybe use Chromium for safety and you should be good. Spoof user agent as needed.
