Chapter 700 jumps very far forward into the future, while the last takes place approximately 2 years after chapter 699, and focuses on how one of the elements of chapter 700 came to be. You wouldn't ruin anything from the movie by reading 700 beforehand. I agree with the other posts; Boruto the movie focuses mainly on Boruto while the gaiden focused on Sarada, nothing from that movie will get ruined either.
