No, but sub placement can be messy since differences in listening distance between the sub and speakers can affect arrival time and phase (many AV receivers compensate for this) and the sub's own internal circuitry can impose a further time lag (receivers which 'measure' the distance based on differences in arrival times of test tones from each speaker also compensate for this automatically since the sub delays the test tone also).
The other issue is crossover frequency. The higher up mains cross over to subs, the more likely it is that you will perceive the sub as another source. There is evidence that crossover at 80 hz is OK on this point and this is a recommended crossover point for HT setups but lower is better/safer.
In theory, if the crossover point is low enough so that localisation is not a problem and arrival time and phase are compensated for, it shouldn't matter where the sub is placed. You would then place the sub where it worked best in the room and there's been a huge amount written on that. A good place to start is always the particular manufacturer's recommendations.
