It is once you apply enough Carson's Rule to it. (At this level, the term CW is usually used in contrast to pulse modulation, rather than all forms of modulation in general as would be the understood usage at HF.)
That's the question, whether the ADS system has much modulation BW at all. HUSIR has 8 GHz, which is a fair bit. My guess is that the ADS uses its gyrotron(s) as single-stage oscillators, like the giant microwave oven it is, rather than as amplifiers for a carrier that's generated and modulated at a much lower level. Modulating a CW gyrotron oscillator directly would involve manipulating high magnetic or electric fields at unrealistic rates, and any useful degree of signal purity or short-term stability would likely be off the table entirely.
OTOH the .PDF talks about PRF and pulse width, and specifies a 40% duty cycle, so who knows. If it is indeed a pulsed system, I don't see how it differs from whatever ADS uses. The specs aren't particularly challenging.
