I can’t remember if Thorin’s weapon is an Orc-bane, like Glamdring or Sting… but, basically? No.
It’s kind of important to remember that, even in Tolkien’s books, the entire setting is pushing towards a kind of epic of myth. Everyone is capable of feats that are well beyond actual human limits. Whatever issues I have with Jackson’s adaptations, it is a basic concept from the source material he clearly understands.
Given that Tolkien and Robert E. Howard are probably the two most influential writers for modern fantasy, and both of them were prone to that in their own ways, it probably doesn’t matter for your writing.
But, no, throwing a sword with enough force, and accuracy, to impale someone is basically not possible.
