NVMe would be possible if it passed along the appropriate BIOS bootcode. Never tried it, so don't know if it exists or not. (Essentially, does the adapter just create a bridge to the PCI-E bus or does it host the device and supply bootcode? Or do variants exist for each?)
And yes, possible to run swap files from an SSD, it's not a good idea even if your drive has wear leveling. Each SSD has a lifespan measured in total bytes written and this factors wear leveling into that number. Granted on a WinDOS 9x machine the amount of data used or transferred diminishes immensely compared to modern Windows, it's still there. Plus RAM being as cheap as it is, you're often far better off maxing out physical RAM simply for speed's sake. Either way swap files aren't necessary or highly recommended.
Oddly enough I did note one funny thing in my 486 build... the 256KiB of cache on the motherboard transfers at around 30MiB/sec, around USB 2.0 speed factoring overhead. Blazingly fast at the time I'm sure, but kind of hilarious now. Which goes to say that an NVMe would be ridiculously overpowered on an older machine even if it could be made to work.
