I struggle with in Trello is that Lists don't have descriptions. So I'm torn between short (but vague) titles and clear (but unweieldy) titles.
One solution:
TITLE
description
Kludge: —— TITLE ——– description
Which usually will wrap to :
—— TITLE ——–
description

No.
All the keyboard events are consumed, so you cannot enter a linefeed using the keyboard. However if you have text written externally (such as in a notepad) which contains a linefeed, you can cut-n-paste that into the element editor.
However the joy is a short lived, as the text is sanitized as soon as it is submitted; removing all training white space and also collapses the unprintable characters such as the newly created newline.
So in short, No you cannot enter a line feed into Trello's list text.
