yes, it works!
In fact, I was given advice to remove all TB´s and running QA again to get rid of these messages about terms not matching, but your solution should also be fine.
If you don't want terminology checking, you can simply turn it off in the project settings. Click Project manager > Settings > Project QA settings.
In memoQ 4.0, there is also an "Ignore all warnings of this kind" command to ignore all terminology etc. warnings with one click.
