And yes, Goku did already IT that far. Remember during the FNF arc, when Gohan was powering up so that Goku could pick his ki signature? He then proceeded to IT straight from Beerus's realm to Earth, in one go. And Beerus's realm is as far from Earth-at the very least mind you- as the Kaioshin realm is. Which equates to far more than just one galaxy. Depending on which canon you're basing yourself on(whether it be the anime, or the manga), it can even grow to Universal range due to this.
