So what Steve means is that you can just say:

  This package Y is based on the program X from company Z, but
  has been modified by Debian and others.

or something.  It is not necessary to mention whether X and Z are
trademarks.  But if you want to explain the renaming you can say:

  We have called this package Y because X is a trademark which
  we don't have suitable permission to use.

or some such.
