Not necessarily, in fact probably not IMO. It might be catalytic carbon (maybe even Centaur Carbon) -- which is not at all the same as activated charcoal carbon. A Centaur Carbon filter should be on the front. I don't know about getting air in with that controller though. The people who put in that dual tank softener were not cheaping out, and I really doubt they would have put Coconut charcoal in that position. Now the way that it would make sense to have activated carbon there is if it was preceded by a chlorine or other oxidizer injection system.
