Does the program you start the render from count as a render node?

I am running Corona from Cinema 4D and it looks like Corona comes with 1 render node, can you render on the computer you launched the render from and also 1 node, which would be rendering on 2 computers total, or does the main application count as a Corona render node?

You need an extra render node for the second machine. The moment you start rendering on the main workstation the render node license you have will be engaged.
