Can a 4x100 wheel fit a 5x100 bolt pattern?

No, a 4x100 wheel cannot fit a 5x100 bolt pattern. The numbers refer to the number of bolt holes and their spacing; a 4x100 wheel has four holes spaced 100 mm apart, while a 5x100 wheel has five holes. These two configurations are incompatible, making it impossible to mount a 4x100 wheel on a vehicle designed for a 5x100 bolt pattern without adapters, which can affect safety and performance.
