Nano machines didn't exist back then, and as Big Boss stated in MGS4 that he was in a nano machine induced coma after Zanzibar Land. My best guess is that he was blackmailed into rejoining The Patriots just before MG 1 and 2. While working on Outer Heaven and then Zanzibar Land in order to remove The Patriots from power. When you also think about it. Did he really turn villain? From the view of someone who has never played the game before: Yes, he would be the villain. But after that final scene in MGS4 in my opinion. He was vilified when he was actually a hero trying to save the world. Not to far from what The Boss had to do in "Snake Eater"  The Patriots used Solid Snake to take care of the biggest threat against them at that time and that was Big Boss.

Not to mention keeping him in a coma after "Ground Zeroes" through "Guns of The Patriots" is extremely impractical as well as dangerous. That would mean keeping him in a drug induced coma from 1975 to the mid or late 1990's when he then would have been shifted to a nano machine coma until somewhere between 2012 and 2014. Now keeping someone in a drug induced coma for that long would have perminant, if not fatal side effects. Then shifting him to nano machines, to sustain the coma. The nano machines would have to be the kind that vamp had, the kind that repairs, because of the weakened muscles. The possible brain damage and organ damage. Not to mention if these nano machines were able to repair damaged tissue, they would not have needed a donor arm from Solidus because his original severed arm theoretically would have been regenerated.

Long story short. I think it is the same Big Boss.
