No, the system-level memory map is different.
Ah, that's a shame but not really surprising, and obvious in hindsight.

I suppose one could add trap-handlers for memory accesses but that's all a bit much compared to the pragmatic compile it twice approach.
If you want a single UF2 file which you can drag onto either a Pico 2 or Pico 1, you can achieve this by building an RP2350 and RP2040 UF2 separately (from the same source) and concatenating the two files together. The UF2 families are different, so the UF2 bootloader can filter out just the parts intended for the current device.
Yep, that's what I've been doing, and it seems to work well, though not tried it with an actual RP235X - 'picotool' doesn't like that though, which is a bit annoying.

Oh, and a belated thank you for the excellent job done you've done with Hazard3.
