I doubt it. The carbon acts as the conductor to the cement's insulator. Adding rebar is likely going to cause issues. I expect this wont have applications in high rises, more akin to a cinder block or poured concrete foundations that wouldn't need reinforcement.
Might honestly be a fatal flaw for most applications where we currently use concrete, but maybe purpose built devices would still make sense at power plants/etc.
Epoxy coated rebar is already a thing, so insulated rebar shouldn't be that big of a deal - if epoxy isn't enough already.
Maybe different for different regions but I'm pretty sure foundations will generally have a small amount of steel mesh at a minimum to stop cracking. Someone please correct me if I'm wrong though and hopefully they find a way around this limitation as well. Carbon fibre can also be used from memory but I haven't seen it that often presumably due to cost.
Maybe for home foundations and the like, glass fiber rebar could be used.
