No, it won't work (_remove only works on variables which contain items
separated by whitespace).

As a workaround for Yocto 2.0 and earlier, you can over-ride the
complete final value of BBMASK from your local.conf.

If you are using Yocto 2.1 or later then BBMASK does support multiple
whitespace separated regular expressions. So then you can update the
BSP layer to use:

  BBMASK += "msta-xxxx/xxxx/yyyy.bb"

and then:

  BBMASK_remove = "msta-xxxx/xxxx/yyyy.bb"

from local.conf should work.
