A 32-bit application will not open in a 16-bit environment.  It will fail!
The only way to know what code is inside the *.exe is to try it.

Hi guys.  The first two bytes of a 32-bit EXE should be "PE".  Older
EXEs have "NE" or "MZ".  DOS programs begin with binary data.

All relocatable executable files begin with "MZ", and can be started from the
DOS prompt. But under DOS only the "stub" executes, and usually states that the
program can run only under Windows, or tries to start Windows itself. The "NE",
"PE", "LE" etc. magics reside at the begin of the Windows executable part of
the file, not at the begin. Non-relocatable DOS programs have no magic ID, and
usually have a *.COM or *.BIN name.
