Could Ramillies's secondary guns damage the German ships?

Could Ramillies's secondary battery damage Scharnhorst and Gneisenau when they closed to effective 11-inch range?

Yes; her 6-inch guns could reach that range and add damaging fire, although their casemate arrangement imposed limitations.

Ramillies carried seven 6-inch guns on each side in addition to her main battery. Their maximum range exceeded 21,000 yards, so they could contribute inside the roughly 18,000-yard range discussed for a decisive engagement. Casemate mountings imposed handling and sea-state limitations, but the shells remained dangerous to exposed systems and lighter structure. Closing to penetrate the battleship's armor would therefore expose the raiders to more than her 15-inch guns alone.
