Short answer is it's fine.

The more nuanced answer: because pausing the print may allows the part and the printer (heated bed, nozzle) to cool down significantly, there's a chance your part will shrink or warp enough that when the print is resumed, you could end up with seam lines and/or gaps at the point where the stop and restart happened. The extent depends on the amount of cooling and the material. In some cases, people use temperature-sensitive bed material that results in the print popping off the print bed when cool. If that's the case, long period of cooling can still result in a failed print, but at least you won't be running your printer continuously without fresh filament.
