Cross-referencing with this picture here ([link|https://guide-images.cdn.ifixit.com/igi/RbnN3EPj5kKlekQm.huge|RbnN3EPj5kKlekQm.huge (1600×1200)|new_window=true]), we can see that the component you are looking at is on the edge of the board (above the dark blue box). We can see there are more along the edge (above the orange boxes). It doesn't look like this connects anywhere, but it could be a resistor if it does. Chack to see if there are more along the edge as seen in the picture. The iage found on iFixit may not be correct due to design changes, but should be similar.
