yes.
the principle of relativity which was discovered as far back as the 17th century essentially states that motion and position of an object are RELATIVE to the frame of referance of the observer.For example,from the earth's POINT OF VIEW, the sun moves.(which is why we say that the sun rises in the east & sets in the west).
But from the sun's frame of referance,it is the earth that moves around it. this is an obvious & established fact and is known as principle of relativity.
when Einsten came around, he proposed the special theory of relativity which predicts stronger & surprising results.For eg,all along,the principal of relativity assumes that the length of an object does not change when it's in relative motion.it also assumes that the time passed on a moving frame is the same as that of a stationary frame.these assumptions were proved wrong using special relativity.
So there is no reason to 'mix' up the principal of relativity & special relativity.for a fuller treatment,you may visit the folowing webpage:
