Yes.
The RCC and Control Rig are complimentary tech, but they still do distinctly different things.
RCC: it's basically a super-duper commlink. In addition to everything a commlink does, it allows you to share Autosofts out to your drones. It also reduces Matrix Noise.
Control Rig: cyberware that allows you to perform the Jump Into Rigged Device matrix action.
You can use them both together naturally, but you can still use one without the other. For example, you can use a Control Rig with a regular commlink since you don't care about Autosofts (you'll be jumped in, duh) and if you don't need the Noise reduction. Indeed, if you're physically sitting inside the car you want to Jump Into, you don't even need an intermediary matrix comms device... you can just interface directly with the car itself. And directly to your question: You can use a RCC to share Autosofts out and reduce Noise even when you're not Jumped In.
