Can a chord also be classified as a radius?

No.

A chord is a straight segment that joins two points of the circumference. It starts at a point in the circumference and ends at other point in the circumference.

The radius goes from the center of the circle (which is not on the circumference) to one point of the circumference.

The diameter is a chord (the largest chord possible); but not the radius.
