You can write a music function to do it:

stripTags = #(define-music-function (parser loc m) (ly:music?)
        (music-map (lambda (x) (ly:music-set-property! x 'tags '()) x) m))

one= {a'' \tag #'A b'' c'' \tag #'C f''}
two = {\keepWithTag #'A \one }
three = { \tag #'B \stripTags \two \tag #'E a'' }

{
  d'' \keepWithTag #'B \three 
}

Hope this helps--
