Not really.  You might be able to port your DOS CGA program to an OS/2
"text-mode" program that uses the CGA graphics video modes, but
this is not a good idea and would impose a lot of restrictions.

In general, a PM program is one written to the PM API.

The PM API is usually considered as encompassing the graphics-oriented API
functions, such as WinXxxxx and GpiXxxxx.  The base API is usually
considered as encompassing the DosXxxxx functions.  There is also the
16-bit text-mode API which is effectively superseded in a PM program, such
as VioXxxxx, KbdXxxxx, and MouXxxxx functions.
