Yes. There are actually several inside Beatles references in this film.
Just after the film opens, there is a scene of a high school dance, which shortly cuts to a similar scene in an underground club in Liverpool, England. The song is the same as in the high school dance, but the band is much more "blue collar" - much grittier. This is a clear reference to the Beatles early years playing in "The Cavern Club," right down to the vaulted brick ceilings.
An elderly shipyard employee who gives Jude his paycheck says he thought he'd be doing something different when he was sixty-four, an allusion to the song "When I'm Sixty-Four."
Prudence first enters the New York apartment where the main characters live through an open bathroom window, a humorous reference to the song "She Came In Through The Bathroom Window."
Max and his friends regularly hit golf balls off the roofs of the Princeton campus buildings: the golf club being a "silver hammer," and is responsible for his and Jude's re-acquaintance and subsequent friendship. When Max and Jude first see their apartment, Sadie comments that Max seems harmless, but could have murdered his grandmother with a silver hammer, and in another scene Max is shown holding a silver hammer, both unsubtle references to the song that inspired Max's name, "Maxwell's Silver Hammer."
Apple Corps (pronounced, "core," as a pun) Ltd., the company founded by the Beatles in 1968, is obliquely referenced when Jude is trying to draw a green apple, then slices it in half and tries to draw it again, thus producing the two images used for that company's record labels. When he becomes frustrated with drawing the apple, he obsessively begins painting images of strawberries. Later, when Lucy tries to get into the building where Sadie's own recording company is located, and where the rooftop concert is taking place, we see one of the strawberry paintings as the company logo, with the name, "Strawberry Jams," an obvious take on Apple Corps, complete with it's own pun.
The rooftop concert toward the end of the film references the Beatles' famous impromptu rooftop concert atop their Apple offices in January 1969 - their final live performance, which was also broken up by the police, as it was in the film.
The people in blue during the Mr. Kite sequence resemble Blue Meanies from Yellow Submarine.
The club where Jude is first seen is a reproduction of the Cavern Club where the Beatles used to play in Liverpool.
The neighborhood where Jude lives, with the brick houses, looks exactly like the neighborhood where the Beatles used to live, and which can be seen, for example, in the 'Free as a Bird' video.
Jude's girlfriend Molly is later seen with a boy named Desmond, a reference to the couple in "Ob-la-di, Ob-la-da."
