The answer is yes, but it depends on the environment. Please tell more about the situation you have, and share some code you have.

What environmental specifics do you need? I'm not quite sure what that means. As far as code I don't even know how to go about sending an interrupt, what I'm trying to accomplish is more of general learning because I intend to do some fun things like making an OS, I'm currently playing around in the windows 7 (7601) kernel through a program I run that allows me to run bytecode in the kernel through CVE 2018-8120.

you should be able to run code on any core in kernel mode. I'd find out how to do that first. in user mode you could spawn a thread and divide by zero from there, that would be like an interrupt.

I guess that the term you're looking for is IPI (=Inter processor interrupt). But that is only available at a very basic level (OS level). IIRC this can be issued by the Local APIC.
