Yes! Each Cinema 4D Commandline subscription is bundled with a Redshift CPU entitlement, so you can use Redshift CPU to render via your CPU render farm. To make use of client GPUs, you'll need a Redshift subscription for each client.
Note that Maxon App 3.0+ must be installed on each client to provide licensing. Teams Floating licenses assigned via Teams Dashboard can be used, but Maxon License Server is not supported.
