Yes, as long as you gesso it first. Gesso is a white acrylic paint you can get at any craft or art store. Without Gesso, the cardboard will absorb much more of the oil paint and will peel and crack faster. Gessoing will save you money on oil paint and touch-ups! To gesso, take a large brush and a dish of water. Paint the cardboard with a thin layer of the gesso, thinning it out with the water. Make sure all your strokes go in one direction. After you've done one thin coat, let it dry. Then do another one, only with the strokes in the other direction. After that layer has dried, do a last coat in the original stroke direction. Remember to let the gesso dry completely before starting to paint with oil paints!
Varnish preserves wood better than paint.
Paint can be applied over varnish, but it needs to be a compatible type of paint for the type of varnish, and the surface needs to be prepared by removing loose material, dirt and sanding. If it is not a compatible paint the surface needs to be etch primed. Contact a local paint supplier for advice.
You can't without destroying the cardboard.
No, paint itself does not have the ability to bend cardboard. However, when cardboard becomes wet from paint, it can lose some of its structural integrity and may warp or bend as it dries. The weight of the paint can also cause the cardboard to sag if applied in heavy layers. To avoid these issues, it's best to use light coats and allow adequate drying time.

You can't without destroying the cardboard.
No, painted cardboard cannot be recycled because the paint can contaminate the recycling process. It is best to remove any paint before recycling cardboard.
Usually yes. You'd be advised to use a water based varnish, and rough up the paint a little before coating.
