It makes no sense for Whitebeard to say that to save face and pride, and then immediately forsake his face and pride to admit he's old, he's going to die, and his time has long past.
Considering that Whitebeard's Haki was full force when he struck Akainu, I doubt it. When he tried to use CoC against the executioners, he caught a heart attack, but that doesn't mean his Haki was weakened.
