Sure. You'll be going without service until you upgrade to a wideband package, or TWC stops deploying DOCSIS 2 hardware entirely.
Not really true. TWC requires Turbo and above to use Docsis 3 modem. If you were to rent the modem, you can request a Docsis 3 modem, however, the SB6141 might not be available in your Division but there's nothing wrong if you ask for it.
