OP - no. Disc wheels and your frame have different hub dimensions. Your frame is a 135mm OLD rear end. You will need to use hubs that have been designed to run on QR mtb applications or specifically for CX. As for rims - as others have mentioned you can run anything you want. It being disc specific or not is a non-issue considering the extra weight involved with the rotors and hubs far outweighs any small gain in removing the braking surface on the rim.
Tubeless discussion - As of now I have and will continue to advocate that tubeless applications perform great for mtb but not at all well for CX. Those who have them perform well are operating at a pressure that is well above what is normally run and achieved with a tubular. This doesn't matter for riding and racing between August and early December in many cases. It will not work for Nationals, worlds, big events that occur after Thanksgiving in the midwest or majority of the CX practicing world/Europe/NE.
Simply put you run a tire at the pressure needed to perform and it will burp....at the worst moment...and you'll be running to the pits with a dripping bike on your shoulder. Seen it a lot.
Road? meh. Tire technology hasn't been there so far. Biggest issue is that all sealants will attack the all tires over time. Not much of an issue on mtb - little more of an issue on road where the forces on the tire are substantially higher.
In general : High air volume: low pressure (Mtb) works well. Low air volume:High pressure (Road) works well. Low air volume: Low pressure (Cross) is a ticking timebomb of burptastic proportions.
As for the last comment on why HED Ardennes pre-builts suck at $1k....uh...because the same rim can be used with amazingly higher quality hubs like a Chris King R45 and still save you a few hundred on the retail price. That's why.
