Which boundary ?
You could use the controllpoints of the curve to check with “Point in Curve” if all Points are in the boundary, ist inside. half of the Points= intersecting and no Points= outside
If your boundary is like a “star” for example, you also have to check for intersection of the curve and boundary. Not that the Points are inside, but the curve crosses the boundary

You could also use the Region Difference component to check if the (inner polygon) - (outer boundary) region is empty (length of list = 0)
