No. The kernel is loaded first thing during boot and is the core of the entire system, as discussed in e.g. this thread. How could you imagine it being replaced with the system running?

There are actually several technical solutions allowing to hot patch a Linux kernel. The most advanced is ksplice which is a feature of Oracle Linux. Alternatives are kGraft (Suse) and kpatch (Red Hat)

AFAIK, even while part or all of the underlying various implementations are open source, kernel hot patching is always a paid service.
