Yes it could.
An ellipse is a specific shape with a mathematical formula and certain qualities (like the distance from one focus to the edge of the ellipse to the other focus is constant).
An oval is not so precisely defined but is a closed curve.
Ellipse
All orbits are elliptical. Orbitis the path of a body as it moves under the influence of a second body. An example is the path of a planet or comet as it moves around the Sun. Planets and satellites that orbit other bodies trace out a path called an ellipse. An ellipse is a closed curve wherein the sum of the distances from any point on the curve to two internal focal points is constant. In everyday life you probably just call this an oval or an egg-shape.
A bell shaped curve often describes the distribution of phenotypic classes of a polygenic trait.
A bell curve shaped graph
s-shaped/curved
That shape is called an 'oval' or an 'ellipse'.

Ellipse circle
A continuous curve surrounding two points will be called an ellipse. Very strictly speaking, the ellipse, circle, etc is the bit inside the curve. e.g. " a circle is bounded by ... "* * * * *Even more strictly speaking, it is any closed curve around two points - it could wobble all over the place.
