In my university the computers have MikTeX installed, but I'm having problems to install and update packages in MikTeX (Error installing packages on-the-fly).
I've never used TeX Live and due to this problem, I'd like to know if a file created in any TeX editor where MikTeX is installed would run without any problem in another computer where TeX Live is installed.
Is there a possibility of conflicting packages or something similar?

As long as the packages shipped are the same, you should not experience problems trying to compile documents with TeX Live which were created using MiKTeX.
But, the same issues you can get when upgrading MiKTeX or TeX Live can also affect you when compiling with different package versions, e.g. updated packages handling things differently, deprecating old ways of doing stuff and introducing new ways.
Be aware that even my largest document (200+ A4 pages, 300+ citations, 40+ packages loaded in the preamble) only needed minimal fixing when upgrading from TeX Live 2014 to TeX Live 2018 in one go. So, from my experience, you should be totally fine doing that.
