In my opinion i say yes Vegeta has been training ever since the tournament of power up until Broly the movie Vegeta even faught Broly base to base something many people did not think was gonna happen considering the amount of power Broly possess(the legendary super saiyan power) Vegeta will for sure be able to handle Moro based off what we see in the dbs broly movie vegeta power has raised a crazy amount. He is still training up to the moro fight goku may even see vegeta as equal or maybe he even surpassed him.
