Since they are based on different CPUs I very much doubt the SD cards are interchangeable.
On the one hand I wouldn't be at all surprised if 0 and 3 had eg mono configurations that weren't 100% compatible. OTOH some of the information upthread seems to suggest that it should be OK to interchange Pi's unless maybe I misread/misunderstood it?

Hmm. Made another new SD card:

1. Flashed using Etcher with Raspbian Stretch

2. Initial updating etc on Pi 3B+

3. Move to Pi0W and install Mono - took around 30 mins.

4. All seems to be running OK.

SD cards should be interchangeable without problem between all models of Raspberry Pi. I routinely do builds on a Pi3B+ (so that installs are fast) then swap the card to a Pi0W for actual use.

The only problem I'm aware of is that an "old" card might not work if you try to use it on a version of RPi that hadn't been released when you built the card - it might not support the features that have just been added. But that is avoided if you perform a full update on the old Pi before swapping across.

All I can say is that this isn't my experience (using recently purchased pi0W, 3B+ and fully updated Stretch). Clearly there must be an explanation for the difference somewhere but I don't know enough about Raspbian or Mono to dig into why. In my systems I definitely need to do the Mono install on the 0W to use it there, though where the install/update steps are done pre-Mono doesn't seem to matter. Fortunately, doing the Mono install on the 0W 'only' seems to take around 30 minutes, which is a slight pain but not too time-wasting.
