Possibly but they have to have open communication with both members wanting to participate. There will be growth and changing as people age and participants will need to adapt and compromise. Desires at adolescence and into adulthood will evolve. Perhaps a solid good friendship is a potential goal but maybe with both wanting same thing.
It happens occasionally. Sometimes I meet couples who have been married 30+ years who say they were "high school sweethearts." However, I believe the vast majority of high school relationships end within a couple of years (including the ones I had) because--like it or not--most high school aged kids have a lot of growing up to do before they really know what they want in a relationship.
While almost anything is possible, there so many variables that are unknown and can happen. Therefore I'd say it is possible but highly unlikely. It would be like playing the lottery, it could happen but it's a very long shot.
