Almost. But there is at least one core library, the C runtime, that is
linked into just about every process that runs. So an update to that
library requires those processes to restart.

Greg Kroah-Hartman, ?Mr Linux Device Drivers?, has said

that running the latest securely-patched stable kernel (important on
public-facing servers, for example) would mean a kernel update just
about every week.
