In my humble opinion, the Beast Titan and Mr. Smith are not the same person. It is true that the burning scar is suspicious, but I found something that I could not understand.

When Erwin was a child, let's say about 10 years old, his father was kidnapped. We can asumme by looking at the pictures that his fathet was about 40 years old.

Now I don't know the exact age of Erwin, but I think it is between 30 and 40 years old. That means that if his father is alive, it would be about 60 or even 70 years. And looking at the human form of the Beast Titan, he looks not only WAY more fitter than Erwin's father, but he does not look like an old man. He even looks younger that Mr. Smith, as we can see on the pictures.

However I admit one thing: the Beast Titan is considered by Isayama the most powerful Titan. He may have powers that have not been shown yet. For example ( especulation ahead) his regenerative powers may be so powerful that he ages slower than regular people, similar to Wolverine on the X Men.

If this were the case, he would be the only Shifter that can do this ( Eren, for example, aged at a regular speed even after receiving both the shifter power and the Coordinate)
