As a different dialect of the language, at least, yes, akin to the
difference between Python 2 and Python 3. (LuaJIT is also a different
dialect of the language.) A good distro will install them as slotted
packages that can coexist.

As Lua's primary goal is to be embedded, applications that run from
the system-installed Lua interpreter are a fairly recent development.
For most deployments you're expected to roll your own Lua.
