I think, the case you describe is NOT about HCL reports (existing or proposed in this topic).
I mean for me, HCL reports as they are today are not giving enough information to make any decision. If we talk about a laptop I would prefer to know how suspend works on it, if the keyboard is ps/2, is wifi works out of box and recovers after suspend and etc. Qubes OS works almost on any hardware, but the difference is in details that can and should be provided from actual Qubes OS running. It can be indeed LiveCD that existed and was dropped (if I remember correctly). But GNU/Linux liveCD does not look a reliable solution to me to make a buying decision of a laptop targeting Qubes OS.
I think it should be recommended. Well, at least in the future advanced reorganized HCL reports compare table. For this purpose can you, please, also fill the detailed report based on this template:
