The Metropolitan Line has unused platforms at Swiss Cottage station, so the

It's not really the same station. Just another one with the same name.

According to Wikipedia (referring to Swiss Cottage Jubilee):

"The new station initially operated as part of a combined station with
the Metropolitan Line's adjacent sub-surface Swiss Cottage station
(platforms 1 and 2 were Metropolitan Line and 3 and 4 were Bakerloo
Line) but the Metropolitan Line station was closed on 17 August 1940."
