Two points.
1. Panoramic generally means wider than about 3x2
2. A curved back camera will produce a different projection than a
cropped down negative from a rectilinear camera. Rectilinear projection
spreads out the edges of the frame to preserve straight lines, whereas
a curved back camera produces a cylindrical projection which sacrifices
straight horizontal lines to keep dimension consistent with distance
from the camera.
I have been experimenting with producing 360 degree pinhole pans by
shooting a series of wideangle photos then stitching them together
using special software, but nothing has quite worked yet.

I'm going to guess that my answer would be that it is a combination of
the angle of view and a format that is wider than a normally wide
format (I would guess that the typical 2X3 aspect of 35mm film would
be condidered wide). Indeed, you could halve a sheet of 4X5, but if
the result was a slit containing a portion of a person's face then I
wouldn't consider that a panoramic image (although I could certainly
see an argument for it).
On a somewhat related comment, you can view my panoramics within the
first link in my signature by going to Projects then Ballparks.
