Yes, in terms of music theory rhythm concepts can be learned. If you're talking about "rhythm" in the sense of being able to "feel" the music and move fluidly with rhythm, that is something that has to be practiced. It's more a matter of getting out of your head, and becoming comfortable with the way the sound naturally makes you want to move. If you're not naturally fluid in relation to rhythm, it can take some practice to become confident in your movement.
