Yes, you can straighten a perspective photo of a document using Hugin's horizontal and vertical control points, and by setting both the input and output projection to 'rectilinear'.
But I don't use Hugin for this. I would open the photo in an image editor, such as GIMP, and use the 'perspective tool'. If you are using GIMP, be sure to set the perspective tool to 'Corrective (Backward)', this way all you have to do is drag the four corners of the selection to the four corners of the paper. Note that the GIMP documentation claims that it doesn't do true perspective. This is wrong, the GIMP homography distortion is identical to that provided by Hugin.
