I not sure I understand your question. Are you asking that
if the vmcore of a particular kernel was collected, and you
you do not have the debuginfo vmlinux that is associated
with it, can you still analyze the vmcore?
If that's what you're asking, then yes, there are ways to do that.
You can rebuild the same kernel, and use the newly-built debuginfo
vmlinux file along with the System.map file of the original kernel,
