Probably not, but maybe.
From a technical angle:
Cisco CableCARDs require certificates to be loaded on the DNCS (headend controller for Cisco systems) that come with new CableCARD purchases. A random CableCARD off eBay won't come with those, and even if i did, I doubt you would manage to get to the headend engineer and convince him to load them.
Motorola CableCARDs actually have the CPMS (the PC that generates the CableCARD pairing data) download them, as needed, from Motorola. The CPMS then sends the pairing blob over to the DAC (headend controller for Motorola systems) This means that from a technical aspect, purchasing a random Motorola card can work.
From a Political angle:
Most operators will not allow you to own your own STBs, even if they are compatible. However, some do, and in fact Motorola actually sold some STBs at retail about 6 years ago. On an operator using Motorola equipment, you may actually get this to work if you are persists. Cisco is almost certainly a no. Also, on really old (10 year old, pre-CableCARD) DAC software releases, Motorola instructed operators to provision the cards as a DCT2000 (really old, basic STB). Someone might be able to convince their operator to do that more easily claiming it is a customer-owned box. However, that would only activate the card (not pair it) so you would only get Copy Freely content. Pairing would need the CPMS' involvement, which wouldn't be needed for a DCT2000, so a sharp technician would notice something up.
tl;dr: Probably not, but maybe
