You are correct about modulated CW in the sense of a carrier modulated by
an audio tone.
However, there would be nothing illegal about sending CW from a sound card,
provided it was a single tone fed into the mike input of an SSB
transmitter. The output would be a single RF frequency and would be
indistinguishable at the receiver end from a "normal" CW transmission.
Whether this is a good idea or not is another matter. 8-)
