If you are 17 and your boyfriend is 20 can you move in with him and his parents at the parents' house without getting them into trouble?

In most states, the age of majority is 18 (in a few it's higher, but it's never lower). Every state considers someone who is 17 to be a minor. If you leave home without parental consent, or being officially emancipated in some manner, then your parents can report you as a runaway. Anyone who takes you in/assists you, could be facing charges for doing so. The exact charges would depend on the laws of your state, but some possible ones are: harboring a runaway, contributing to the delinquency of a minor, custodial interference, etc. The legal age of majority is higher than 18 in four states, Alabama and Nebraska 19, Mississippi and Pennsylvania 21. Interested parties should be cautious and not confuse age references contained in juvenile codes that pertain to marriage, abortion, adjudication procedures and so forth with the state's "real" legal age of majority.
