Write "what" ?
Yes, it's possible to write lua code for this
\setbox0\vbox{hello world}

but it's longer than the two lines before -- AFAIK  you must build
each node by hands
and pack into a vbox (I don't remember how to pack nodes in vlist )
and then print.

I don't know how to invoke line break algo.
In my opinion
\setbox100=\vbox{\hsize=5cm \input tufte }
is much clearer then basic lua code
You  need some lua layer -- maybe there is something in context base folder.
