That it very likely.
There are windows #defines/inline functions that convert HANDLE <=> long.
Remember there are some functions that return handles as long (not void *)

Also, when the windows kernel generates a HANDLE it is unlikely to know
whether the app is 32bit or 64bit - so will only generate 32bit values.

I also remember reading somewhere that the kernel handle table is
limited to 2^24 entries - even in 64bit mode.
