I installed Qubes 4.2 with and without latest Kernel on my Chromebook.
The install went all fine but after reboot I get a: Verify it contains a 64-bit UEFI OS. Message.
I installed Ubunto to make sure Linux would work and it boots fine.
@Dutchy737, I have a feeling that your Chromebook CPU might actually be missing the required virtualisation instructions to be able to run Xen (the hypervisor that Qubes uses).
