Not necessarily from corner to corner.It means that the stripe runs in one of two ways: 1) From the top left corner to the bottom right corner. or 2) From the top right corner to the bottom left corner.

These tops have a diagonal stripe.

If we are talking about mathematics, a diagonal goes from corner to corner.It's still possible to locate the ends of each diagonal as beingnearestto a "corner" even if we have to superimpose the image of a square or rectangle over the object that contains the diagonal.

However, in non-mathematical contexts, a stripe at something like 45 degrees across an oblong shape, or a shield, &c, would still be called "diagonal".
