This cannot work. In general, Arm boards are not the same
as each other, and a binary built to work on one board
(raspberry pi 4) will not boot on another. QEMU doesn't
currently have any emulation of the rpi4 so you can't run
the rpi4 QNX image on it.

This has a bit more chance of working if both QNX and
QEMU support the board model. Here you are probably
running into the problem that QEMU does not emulate
the i.MX6's "boot off an sd card image" process. You
probably will need to pick apart whatever disk image
the QNX build gave you to find the actual guest binary.
(If you're lucky somebody else will have done this before.)
You might also run into issues if QNX tries to prod some
devices on the SoC that QEMU doesn't have emulation of.
