No. While the Portuguese conquistador Magellan was supposedly killed by King Lapu Lapu with a Filipino sword, it Lapu Lapu did not use the Barong that inspired Dooku's weapon. The legend is that Magellan was killed in single combat by King Lapu Lapu with a type of straight-hilted Filipino sword called the Kampilan. The Barong was a sword used by the Muslim Filipino peoples of the Southern Philippines. King Lapu Lapu ruled in the central part of the Philippines and was not a Muslim but a Visayan animist.
