No. Definitively not. mke2fs -c also runs badblocks(8),
which tries to read every single byte in the partition.
(Optionally you can even have it do a write test. There is
even a non-destructive write test in newer badblocks. Use with
care and do have current backups.)
fsck just checks that the metadata (directories, space used
by files, etc) looks OK.
