Already was thinking about this too... Have both OSes on two different SSDs. 4.1 on a 1TB m.2 card (slot 1) and 4.0.4 on a 512 GB m.2 card (slot 2). 4.1 was installed on the P50 while th 4.0.4 version was plugged out. After 4.0.4 was plugged in again, both cards can be shown in BIOS but 4.1 is booting with it's boot screen cause it actually isn't aware of the second m.2 card, which should be quiet normal. GRUB have to be edited.
