Quoted By:
Takara has more or less dropped the name Convoy, they have for years.
The only leeway is the Masterpiece series which is meant to be faithful to the original Japanese shows, but anything part of mainline Generations (which Haslab is supposed to be, they're branded as part of the WFC/Legacy toyline) has to use the English names.
And even Masterpiece has exceptions. Pic related had to be called Leo Prime because he's technically an OC and not beholden to the original name rule.
