my reading of the latest link annotation dictionary definition seems to indicate 
that it can be a rectangle /Rect entry or



> QuadPoints

> array

> (Optional; PDF 1.6) An array of 8 × n numbers specifying the coordinates of nquadrilaterals in default user space that comprise the region in which the link should be activated. The coordinates for each quadrilateral are given in the order

> x1 y1 x2 y2 x3 y3 x4 y4

> specifying the four vertices of the quadrilateral in counterclockwise order. For orientation purposes, such as when applying an underline border style, the bottom of a quadrilateral is the line formed by (x1 , y1) and (x2 , y2).

> If this entry is not present or the viewer application does not recognize it, the region specified by the Rect entry should be used. QuadPoints should be ignored

> if any coordinate in the array lies outside the region specified by Rect.


it doesn't look like you can get a generic path region as the clickable.
