That's not quite true.....BSP 1 1/2 is 11 TPI and NPT 1 1/2 is 11.5 TPI,
NPT is a tapered thread, BSP comes in parallel BSPP and tapered BSPT.
NPS is the parallel version of NPT.
You can force an NPT into a BSPP at this size but, as Bill says, it will leak under pressure.
This situation is not under positive pressure, so you could probably get away with the bodgy fix of NPT into BSP + sealant....lots.
But it would be better to use a BSP fitting.... of course.
