You could run a virtual machine with Zorin, but the only mention of a VM for Chromebook i can find is this article by Google, and honestly, it doesn't look worth the time and effort.
Viewing post in OOf i wouldnt be able to use Zorin OS
I forgot to add a link to the article I mentioned. Here it is.
https://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices...
Its probably not gonna be that useful, but you (or someone else) might like reading it.
