Can we? That Wikipedia page is inconclusive, and thus article says:

During Edward I’s 1304 siege of the castle, English forces deployed the recently invented trebuchet, a weapon first documented in the 12th century. A cousin to the catapult, trebuchets were capable of hurling boulders weighing more than 100 kilograms hundreds of meters. One at Stirling, dubbed “War Wolf,” “was the biggest trebuchet ever built at that point,” Buckberry says. Eyewitness accounts confirm the giant siege engine was used during the 1304 battle, tearing through two stone walls “as an arrow would fly through a piece of cloth.”

Accounts of the battle don’t mention any trebuchet casualties. But Buckberry says Skeleton 150’s injuries strongly suggest at least one defender was hit from behind by a flying boulder, launched by War Wolf or one of the other siege engines arrayed outside Stirling Castle’s walls. “It’s a huge amount of energy delivered in milliseconds,” Waltenberger says. “In skeletons from past times you rarely see this.”
