For specific values of "safe". ;-)
The mistrimmed takeoff tests for certification generally consider the stab at one end of the band and the aircraft (weight, CG, etc) corresponding to the other end. So if no additional failures or unusual circumstances arise, you are indeed "safe".
If "something else" does happen, though, being fully (or partly) mistrimmed could result in a degraded ability to cope with that event.
