NVMe is a new interface think how PATA was displaced by SATA. Here we are displacing AHCI/SATA with NVMe/PCIe it's a very different interface. So you can't use a PCIe SSD in a SATA based system.
 
Depending on the MacBook Pro or iMac Series it will have either an AHCI or PCIe interface. Here's a better way to understand the complexities:

The other issue with PCIe is the number of lanes. Most of the PCIe/NVMe are 2 Lane (x2) and most of the Mac systems support 4 Lane (x4).
 
The other factor here is the Apple to M.2 adapters being sold. Many are not very good! We tested 4 different ones and most dropped data blocks (CRC error) so over time you'll likely wear out the SSD soonersooner and could end up with data loss. And the speed won't be as good as the real Apple drive our even one of the SSD's designed to work in an Apple system (OWC & Transcend). I don't recommend using the adapter, I do recommend using OWC & Transcend's SSD's!

As far as using something other than the real Apple drive I don't know of anyone trying. Even OWC and Transcend limit their support to the SATA drives in the iMac's as it's such a big job to get to the blade SSD.
