100? No. 0x100? Yes. From the Linux/i386 boot protocol:

The kernel command line is a null-terminated string currently up to
255 characters long, plus the final null.  A string that is too long
will be automatically truncated by the kernel, a boot loader may allow
a longer command line to be passed to permit future kernels to extend
this limit.
