Yes; Or, easier yet, add spacers to the drive side behind fixed cup until it just barely makes it... OR use a Phil Wood unit or similar, and dial it in by moving the bbkt spindle outward to right until it just clears...

John Clay asks" ...when on the small ring and smallest two cogs the chain rubs the inside surface of the large ring. It's a Stronglight 99, 48/28 with shortest BB spindle projection on right side possible. Is that a known issue with wide range double arrangements? "
I have set up several vintage bikes over time with wide range double cranksets. Try a BB spindle the next size longer/wider on the crankarm side.
