No. Macdonwald was "unseamed" (killed) by Macbeth in Forress, Scotland. The Thane of Cawdor was captured the previous day at a battle in Fife (over a hundred miles away.
We hear of the execution of the Thane of Cawdor in Act I, scene iv; Macdonwald already has his decpitated head placed on the battlements in Act I, scene ii.
Hence, they cannot be the same person.
MacDonwald the Thane of Cawdor(Whoops! Macbeth does, in fact, disembowel and decapitate Macdonwald, but Macdonwald is not the Thane of Cawdor.)
After Macdonwald's defeat, the new trouble that arose was a rebellion led by the Thane of Cawdor against King Duncan's forces. The Thane of Cawdor betrayed the king and fought against him, prompting further unrest and conflict in Scotland.
Duncan calls Macbeth "valiant cousin" when he hears he has defeated Macdonwald.
At the beginning of the play in act 1 the Thane of Cawdor (the earlier one, not Macbeth) is a traitor, and also a guy called Macdonweald whom Macbeth defeats.
In Act 1, Scene 2, lines 52-53 state "Assisted by that most disloyal traitor The Thane of Cawdor, began a dismal conflict..." The original Thane of Cawdor was executed for treason.
Macbeth was the Thane of Glamis and one of Duncans generals. After killing Macdonwald, Macbeth became the Thane of Cawdor, and later the King of Scotland (after killing the king)
Macbeth and Banquo battle the rebel forces led by the Thane of Cawdor and the Norwegian King Sweno after defeating Macdonwald.
The the traitors at the start of the play are a rebellion of Highlanders and Islanders, led by Macdonwald and Sweno, the king of Norway who was assissted by the Thane of Cawdor. King Duncan orders the execution of the Thane of Cawdor and hands his title to Macbeth as a reward.
The three enemies of King Duncan mentioned in the scene are the Thane of Cawdor, the King of Norway, and Macbeth. The Thane of Cawdor is sentenced to death for treason, while the King of Norway is involved in a rebellion against King Duncan, led by Macdonwald and Macbeth.

He gives him the title thane of Cawdor since the other Cawdor was a traitor
After learning that he killed Macdonwald, the Thane of Cawdor (the traitor of Scotland), Duncan makes Macbeth the new Thane of Cawdor. He makes Macbeth the Thane because of his valiance in battle. After all, when a battle is done now-a days, awards and battle decorations are handed out, and the guys who were the bravest, most valiant soldiers are given awards like the Medal of Honor. Except that Macdonwald (whom Macbeth unseamed from the nave to the chaps) is a totally different person from "That most disloyal traitor, the Thane of Cawdor" (who was captured and later executed "Is execution done on Cawdor?"). In fact, they must have been involved in two totally seperate battles (as indeed they were historically) because Macbeth had no idea that the Thane of Cawdor was a traitor or had been condemned when the witches predict that he will be Cawdor or when Ross announces that he has been given the title. He could not have been involved in that battle. Macbeth was given the title of Thane of Cawdor for his valour in battle all right, but not because he had personally defeated the previous Thane. Macbeth never fought the previous Thane.
