Sorry, but 'No'. The intent of --no-color is solely not to use ANSI color
sequences. Cursor movement and line clearing is used if stdout is a (not dumb)
tty. These forms should emit no ANSI codes at all:

  zypper ... | cat
  zypper ... > outputfile
  TERM=dumb zypper ...

We'll update the man page to point this out more clearly.
