No, not if Vader and Anakin are two separate people, and Vader actually did killed Anakin.
Oh, wait, maybe I see your confusion...
Vader and some unnamed woman (perhaps a Sith Lady who was part of the 'seduction' to the dark side) have Luke as their child.
Anakin and Lady Skywalker have Leia.
Lady Skywalker, to protect Leia from the Emperor switches the children to throw Vader off the track, so he'd end up killing his own child while Leia is safe and sound with Bail.
Obi-Wan, of course, would not be aware of this, he'd actually believe that Luke was indeed the son of Skywalker. Yoda, of course, would know of the deception, or the Force would guide his thoughts to this conclusion.
