It is possible - see the screen-shot.
I moved the red-axis line so it was easier to pick, and relocated the curve so that its start aligned with the line's start along the green-axis.
The initial offering was a mess because the start/end clash, BUT using the down-arrow toggled that and the bent form looks OK to me ?
It's also usually a good idea to make the line and the curve the same length - your curve is ~2.2m shorter, using Entity Info...
