"Everybody's Got Something To Hide..." is about John and Yoko. He was "bragging" about how they were willing to live a transparent life and be completely open, as opposed to the more closed, circumspect, even paranoid view of many of those around them (many of whom were deep(er) into drug abuse than John and Yoko).
There are a ton:
"Every Breath You Take", The Police - Love song? Nope. it's about a possessive lover stalking and spying on their partner.
"The One I Love", REM - Love song? Nope. Contemptuous dismissal of a partner.
"Big Ten Inch Record", Aerosmith - Steve is not talking about an old school, 78 RPM blues record.
"Pink Cadillac", Bruce Springsteen - Not a song about a car (in fact, Bruce declined to allow Bette Midler to record her own version because he was embarrassed about his original intent - yes, he meant THAT - and didn't want any embarrassment to extend to her).
You can list probably 100's of blues songs in this same vein. If you're really meaning more oblique references, and not just euphemisms to sex, there are still several of those:
"The Ocean", Led Zeppelin - This was a metaphor for the fanbase that exploded exponentially in the first couple years of the band; they went from an experiment ("The New Yardbirds") in 1969 to playing multiple nights in the LA Forum in '72, '73.
"One", U2 - For all his faults, Bono is a MASTER at lyrics that cover multiple bases. A metaphor for Jesus' betrayal by his disciples? An expression of the complicated relationships within his band? An expression of faith to his long-suffering wife Ali? An observation of the amazing reunification of Germany? All of the above, and none of the above.
"The Green Manalishi", Fleetwood Mac - Oringally a "fever dream", this song has alternately been attributed to addressing "jealousy" and "money" (which is the ultimate explanation offered by it's author Peter Green).
