That depends on whether the dryer is gas or electric. Gas dryers vent some excess fumes with the wet air. It's not terribly dangerous when mixed with outdoor air, but when trapped inside with closed windows it could cause a problem.
With electric dryers, you can vent inside as long you you realize the air can contain over a gallon of water per load and make sure you deal with the moisture.
