Yes. Though the actual ships would be longer.
I can't remember if they lengthened it between when it was a STOBAR representing CV-16/17, and when it was CATOBAR representing CV-18... I have a feeling that they didn't lengthen it.
If they didn't lengthen it, then it wouldn't be a surprise if they didn't lengthen it for the current/suspected CVN representative conversion either.
edit:
An estimate on GE of eyeballing the flight deck width, based on the extended flight deck width on the starboard side, which looks like it is "in line" with the building near that intersection (circled red).
I am quite comfortably getting 78m, maybe even 79 or 80m, all of which are of course rather large, and puts it in the same flight deck width as Ford. The overall flight deck geometry obviously will determine how much flight deck area it has to work with.
And here's what a Ford looks like next to it, assuming both have the same maximal flight deck width of 78m at their respective widest points, bookended with their bows at the common point.
Edit: also added CV-18, scaled the same way
That aft/rear area with the foundations on the current revised mockup does look reasonably like where a smaller more aft placed island would go, and it also naturally would imply that there is a substantial part of the aft hull and flight deck which is not structurally represented on the mockup (reasonable)
