no
the tread/track is completely different than the WH model
there are spikes on the sides of the spiked roller thing - WH model has none
the roller sling is slightly smaller - than the WH model
there is some sort of X insignia on the front of the turret - WH model has a plaque
it has a small gun on top of the turret, none on WH model
the front of the turret has 3 pods where the WH model only has a single flat space with that plaque thingy on it
I don't know how you can even tell what the tread/track is on the 40k model, but the one side pic you can eve see it it looks damn similar.
Spikes on the side, I certainly see spikes or bolts, but definitely something sticking out on the sides of the 40k models roller thing.
You realize the X insignia on the C&C thing is painted on to a box extruding out which is right where the one for the 40k is.
You win here, they added a gun on top of it.
If you can't see that it is a blatant copy of the 40k model you are either blind, a fool, or both. Otherwise you are just trolling.
