They can, and they (usually) do.

No.  Linker relaxations can only work the other way: replace longer
jumps/calls by smaller ones.  The "relocation truncated to fit"
message means required information has been lost (because it doesn't
fit into the target address field), so the error is already fatal at
that point.
