No need to guess, that certainly is true - a single audio tone transmitted
without a carrier present will produce a single signal at a frequency of the
carrier + or - the tone pitch (depends on the sideband).  The amplitude will
of course depend on how strong the audio signal is, but it could develop as
much as the CW signal before driving the signal into a non-linear region
(that non-linear maximum will depend on the transmitter design - I do not
believe that is any need for concern on the K2)

--------------------------------

A few of the 1960's-vintage SSB rig designs used exactly this method of
producing CW. It quickly fell from favor because the suppression of the
opposite sideband and even the carrier suppression often was not good enough
to avoid unnecessary and perhaps illegal levels of spurious signals. Some
SSB rigs had no more than 30 dB of opposite sideband suppression, perhaps
less. That's about five S-units, so an S-9 signal would have a image signal
at about S-4 somewhere between 1 and 2 kHz away (twice the modulating
frequency).
