It would get you past this particular error, but you would just hit another error. The real issue is the compilter used to build the kernel must also be the compiler used to build the module. If you really need to run 5.18 kernels on Fedora 34, and need to build external modules for them, you will have to recompile the kernel yourself on an F34 host.
