It is not secure because it is not fixed for these issues:
https://meltdownattack.com/
If you're CPU is not listed there (unlikely) or your use case does not need that much security( depending on your application) you can stay with 4.1.

Fixing these vulnerabilities is a lot of work and no one will fix them for old OS.

I am just trying to know why 4.1 kernel is insecure ? I have try to look but not able to get right answer.

Could you please give me hint or link. I only see it is going to EOL by May 2018.

Yes, why would you use a kernel that is going to be end-of-life in a few months, in the year 2038?  What is going to keep it "secure" until then?
