I'm afraid he can.
Here Minato explains FTG works on whatever his chakra or he himself is touching in some way.

Notice Naruto asks him
why didn't he make Hiruzen jump. His chakra was no touching Hiruzen or he himself was not touching Hiruzen in anyway, thats why he couldn't bring Hiruzen as well.
Here a few fodders are about to be killed by the God Tree.

How did Tobirama do this? After Minato shared all his chakra with Naruto who then shared it with the SA for them to escape Jubitos Barrier the whole alliance was now linked with Minatos chakra, then Tobirama linked his with Minatos. Tobirama made them jump to him because they were touching his chakra (remember its linked to Minatos). He was no where near them to be seen and he
teleported them to his location.
In other words, as long as Minatos chakra (seals) are on those Kunai, he just teleports them right back to his hands no matter what. Another reason why hes so haxed.
