As a former poster used to say 17 is not 18-lite. The age at which you can move out with no chance of being dragged back home and grounded for the year, is 18. In some states older, but in no state is that age younger than 18.
If you are in the state where your IP address is, you've probably heard rumors that you can legally move out at 17. That is NOT the truth. Because of an anomaly in your state law, SOME but by no means all, law enforcement officers are reluctant to take home a 17 year old who is in a safe place. However, not all LEO will take that position, and there is nothing in the law that will prevent your parents from picking you up bodily and taking you home themselves. (That same anomaly will make some LEO reluctant to interfere if your parents choose to do that.)
And make no mistake, if your parents make enough of a fuss, the answer is YES your boyfriend can go to jail if he lets you move in.
