If you're only doing a few push-ups a day, then yes you can do them every day if you want. The question would be if you're actually accomplishing anything.
If you're doing any kind of real strength training, 2x or 3x a week is appropriate. The body will certainly adapt at that frequency, if the intensity and volume are right.
