Should work if you use the correct supported SMBIOS. On desktops, Mac Pro 6,1 works, even the HD4000 will work. Not sure which SMBIOS will work for your laptop. You could probably use MBP 11,1 and spoof the graphics as Intel Iris 5100. Even that may not be necessary. Give it a try.

I use MBP 11.2 on my Probook 4540s, i7 3840QM, HD4000. All working like a dream.
So the HD4000 graphics works without spoofing anything newer like Iris 5100 ?

I have a question regarding Ivy Bridge and Big Sur. Why did Apple leave the Ivy Bridge graphics kexts intact even though the 2012 and early 2013 Macs aren't officially supported by Big Sur? That seems odd to me...
