No, that's not allowed*.
Traditional Method/Methode traditionelle is used to denote bottle fermented wines, unless other protected terms are used , such as Cava in Spain and Cremant** in France.
*except in Champagne where no one uses it because the designation Champagne defines the method of making (and lots more as well. Methode champenoise is not allowed because it uses the 'C' word. As a wine maker/grower & owner in Champagne explained to me, the methode champenoise involves a lot more than just the method of putting bubbles in the wine, from the varieties uses, to how close they are planted, that grapes must be hand picked etc etc -all are encompassed by the Champagne laws.)
* Cremant used to be a Champagne term for a fizz with lower pressure. They gave up the term as a quid quo pro for protection on methode champenoise. Before that happened you could by a Mumm Cramant Cremant, a less fizzy Champagne grown in the Cramant region)
