What do you mean, are you thinking that will damage the ECU? I can tell you that as far as an ECU input is concerned, the absence of a signal is the same as the presence of a signal. 'No signal' merely reads as 'no signal'.
A variable signal, including a zero signal, on the TPS and O2 sensor inputs is perfectly normal. The Motronic handles those signal changes live, just like when the throttle is moved.
Maybe you're thinking that it's generally a good idea to not reach down and unplug the ECU while you're riding? I can get that as a good sort of caution. But heck man, how else can I find out what happens until I try it?
So far I haven't crashed from unplugging the TPS and O2 sensors, while riding.
