Gilbert, Sullivan, D'Oyly Carte, and the members of the orchestra -- and possibly the members of the cast -- were likely to have gotten this joke, but I think the audience was not. It was an "in" joke, even then.
As the name of a musical instrument, trombone is mentioned in 1724 as a "foreign word" for an instrument "more properly [called] a Sackbut." The word, and the instrument, were in common use throughout the nineteenth century.
This discussion is based in part on the definition of the word trombone in the first edition of the Oxford English Dictionary, which requires a little explanation.
To Act I or Act II of Gilbert and Sullivan's The Mikado.
