   It looks like it was changed in an update.  I think the Pi maintains   
   multiple kernels in /boot, so it's possible the same SD card will boot with   
   a 64-bit kernel on a Pi4 and 32-bit kernel on a Pi2 (especially the v1.0 Pi2   
   with a Cortex A7 which doesn't support 64 bit).   
      
   So it may not be that moving the card has affected it, just that the single   
   '32 bit' Pi OS boots a different kernel depending on which hardware you put   
   the card into.   
      
   (this has caused some troubles for build systems which use uname -m to work   
   out whether to build 32 or 64: it returns 64, but the right answer is 32.   
   The same would happen with a 32 bit chroot on a 64 bit x86)
