No. 200A rated fuse holders are only to use fuse links rated between 101A and 200A. The 100A rated fuse holders are only to accept fuse links between 1A and 100A. This is because the inner diameter of the fuse holder is critical to the interruption of fault current. The 200A fuse holder diameter is too large for use with fuse links less than 100A and would not interrupt system faults properly.
