OSM's have a whole processor on board that needs IOS software loaded; PXF 
stuff, etc.  Some of this is in the bootflash for the OSM, but some (or even 
most) is loaded from the IOS image.  I'm assuming FlexWAN is similar, but I 
don't have a FlexWAN to try with.

Also, there are protocols that are only used for WAN, things like APS and 
such.

And you can't trust Feature Navigator to tell you; try comparing the images 
for 12.2(18)SXF16 on a 7600 Sup2MSFC2 versus the same IOS on a Catalyst 6500 
Sup2MSFC2 (same sup/msfc, should have same features, no?) to see what I mean.

Here's a 'show ver' and some other informative commands run from an OSM 
console showing the special IOS running on the OSM's processor, the location 
of the PXF microcode, and the differences in the system: filesystem seen from 
the RP and the CWAN proc:
