No it will fail. You even get quite a lot errors (it is long ago
that I actually tried so I had forgetten this). 

The utf8-code of inputenc is 8-bit orientated: it makes the first
8bit piece of a multibyte char active and defines it so that is
grabs the next 8bit-pieces as arguments. 

In luatex the notion of e.g. the first 8bit piece of an utf8-char
makes no sense, a input char can not be splitted in parts. And so
the inputenc code is really completly useless.
