No.

By the title, he is indeed "Big Boss". However, he is not "Jack" or "Naked Snake" from Metal Gear Solid 3, Portable Ops, Peace Walker, and Ground Zeroes. He is a former medic who was close to Naked Snake, and was deemed the "best man" in MSF. Ocelot and Zero opted to use the comatose Medic to be Big Boss' body double. In doing so, he assisted in creating the legend that is "Big Boss". He would be officially named Big Boss by his friend (and the man he covered for) at the end of the game.

Yes, although the DNA tests prove negative that he is Venom Snake's son. This is because Venom Snake is a copy of the real "Big Boss", and he was proven not to be the father of Eli. However, Eli was completely unaware of this, and his anger towards his father still existed until his own death in 2005. Regardless, he still displayed a distrust of adults, and would likely have been the same way toward Venom Snake whether or not he knew about the ruse.
