NO. A crystal oscillator that could be detuned that far wouldn't really be dominated by the crystal resonance, and might oscillate at an unstable crystal mode as well. An extreme value for detuning might be 1 KHz, and that much would never be designed into an oscillator meant to be a reference, only into a voltage controlled one meant to track a broadcast or tape playback signal.
