Yes, he could, as:
1. Vader wasn't trying to hurt Luke.
"I do not want the Emperor's prize damaged. We will test it...on Captain Solo."
2. Vader wasn't using the Force on Luke, just his lightsaber (someone had a quote saying that if Vader had used the Force on Luke he'd have been owned, even in ROTJ, can't remember the quote, though, I wish I'd have kept it in my profile).
3. At the beginning the fight Vader casually knocks Luke down after I believe just one clash of their lightsabers, but doesn't kill him because he seeks to bring him to the Emperor undamaged. Obi-Wan wouldn't go down after one clash of sabers.
So yes, I do think that TPM kenobi could do just as well against vader is Vader was using only his saber and trying not to hurt him. However, I do agree that no one will be getting pwnd in this fight, but it won't be that close, either.
Yes, he had tried to defeat Luke, but he had not tried to kill him, except for that one certain instance when he tested Luke. In the movie Vader says things like "Far to easy. Perhaps you are not as strong as the Emperor has perceived." That overrides the "had he been able to kill Luke easily, Luke would not have been worth the effort to recruit. But although he had certaintly attempted to defeat Luke, the boy hd held his own." part. The part where Vader holds his saber to Luke's neck, and taks about how Luke is beaten, that also prooves that Vader wasn't going all out - he he had been he'd have killed Luke right then and there. Or at least he'd have cut off Luke's hand then and there if he was going all out to try and win without harming Luke. But no: "You couldn't bring yourself to kill me before, and I don't believe you'll destroy me now."
That quote seems pretty retconned by the films themselves. So yeah, Vader was going at least somewhat easy on Luke, and certainly wasn't trying to kill him, save for that one move.
Somewhat easy?, very easy. In ESB, Vader could have killed Luke in a matter of seconds, if he wanted, he was merely testing him, Vader never at any time in either movie went all out on Luke, he couldn't, in ESB when Luke hit him, 2 seconds later the fight was over.

This is bullshit...he was talking to him...talking some more...oh wait, talked a little more...then 3 seconds after Luke got in a lucky shot on his shoulder, Vader ended it, as if to show how easily he could have destroyed him. Then after that, he could have killed him, but what did he do instead? That's right, he talked a little more...

A. No such thing as luck. Vader was swinging his saber stupid and Luke got him.
B. Did you miss how every OT duel had dialogue in them?
And Luke showed more intelligence and ability in a duel than TPM Obi-Wan. He's shoved down into a pit then jumps out before it can freeze him, then drops down, pushes the steam Vader himself had caused to come out into his face to hold him off, pulled his lightsaber to him and went to strike at Vader all in quick succession (sp?).
Not to mention his jump was so quick and quiet that Vader couldn't even sensed he moved.
