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 trying on 32 Bit micro board with ubifs file system with Linux Kernel 4.1.
And in your testing, did you find any problems?
Also note that the 4.1 kernel is very old and obsolete and insecure, and should NOT be used for any devices in the year 2038.
best of luck!
