Installing NethServer on Red Hat Enterprise Linux?

This is probably a really stupid question but I’ll throw it out anyway and take whatever fallout: I’ve had a Red Hat subscription for several years and don’t see why I can’t simply install Nethserver on that. Has anyone done that and is it alright to do?

I have vague memories, from when we started working on NethServer: it worked.
I think that the current NethServer 7 should work, too.
