[Star Wars] Was it common for Imperial officers to withhold information or straight-up lie to their superiors for fear of death?

Yes, though not necessarily for fear of death.  A lot of the Imperial military officers would 'forget' to report something to make a superior look bad.  On the Executor (or any other command with Vader present) this was a high risk high reward move where your superior might be executed and you field promoted.

There were also plenty of other reasons - bribes to look the other way from criminals, Rebel sympathies, personal reasons etc.  The Imperial military was heavily corrupt in both canons, with a few fairly notable exceptions (Thrawn being the highest ranking one we see).
