Of course he didn’t, the head fell on its own, gravity rules, you know?
Also, after one single person leaves the garage, “the group” is not inside the garage and “the group” still haven’t left the garage, so Kalladin could leave the garage, leave Vin’s head on the ground and run away, and he didn’t use a body part, he used his whole body to do this.
And, while they were exploring the island, “the group” broke down the door to the shed,
after that Kalladin brought Vin’s head while he was alive inside the garage, after Vin’s death, Kalladin left the head outside and went to kill Dalinar, the head fell to the ground and “the group” saw it upon leaving the garage, after that Kalladin once again brought Vin’s head to the garage, this time with him dead.
Plus, a tool or an object like a plastic bag was used by someone from “the group” so that they could move Vin’s head without touching it, obviously this tool or object does not constitute a "device".
One last thing, given “the group” didn’t notice Kalladin wasn’t Vin, a person from “the group” killed Kalladin and placed only his head outside the garage, that way, they didn’t touch Vin’s head, because it was Kalladin’s head, so it’s pointless to argue about Vin’s head when Kalladin’s head is the one “the group” saw right after they left the garage.
