Yes, technically it should work.

Are backup external hard disks, 2.5 inch form factor, USB3, allowed in those places? Those are bootable.

Yes, they may be allowed if hoops are jumped through first.

Or caddies, connected via USB2/3 when you plug any standard hard disk upside down. I have booted from those, too.

I'll have to give it a try.
