One possibility would be to provide flags as explicit parameters as in

#macro M22_INTERN(USE_T1, T1, USE_T2, T2)
...
#if (USE_T1)
   texture {T1}
#end
...
#end

and provide convenience macro wrappers such as

#macro M22_1(T)
   M22_INTERN(true,T,false,T)
#end

#macro M22_2(T1,T2)
   M22_INTERN(true,T1,true,T2)
#end


But actually, I think in your case it is simply possible to write

#macro M22 (TextureList)
...
   object{CSGM22Chassis
   texture {TextureList}
...
#end

and calling it like

M22(texture {BodyTexture1} texture {BodyTexture2})
