Can a guardian move my child out of state?

The existing orders would need to be evaluated closely. The answer may also depend on your visitation rights. If the visitation can still be accomplished without interference the move may be allowed. If your visits could not be accomplished then the move would violate the court order. You should explore filing a petition with the court to prevent the removal of the child and/or modifying your visitation rights. You can also explore whether the guardianship is still necessary.
