The only similarity is the bolt circle SO technically they could be said "to fit" BUT not correctly. There could be multiple issues, primarily with any C5 wheel you would have issues with "inboard" clearance. If you were interested in using them for "just a roller"- it could be said "maybe" but unlikely!

The bolt circle is the same 4.75" dia.
The offset is different. The C5 will sit inboard by the amounts shown below.
I put them on a '94 and they fit without spacers although the rears were visually inboard. The '84 to '87 cars suspension is different and used different offsets than the later '88 to '96 cars. So although they fit the late C4's without spacers, they may not fit the early cars.
84-87 base
16" x 8.5"- 32mm
84R-87 Z51
16" x 9.5"- 38mm
C5 base
17" x 8.5" - 56mm
18" x 9.5" - 65mm
88-96 base
17" x 8.5"- 56mm
17" x 9.5"- 56mm
(also used for fronts on some models)
