yes. Just sand the surface with a 100 grit or 150 grit sandpaper to insure a good bond.
Do NOT DRY SAND if the paint is older than 1978 as it likely has lead in it which is toxic. Spray with water, then wet sand to not create lead dust.You can but it wont last, you will have a bigger peeling mess.
Water based paint such as latex and acrylic do not adhere well to oil paint. In order to paint over oil paint you must sand the surface and prime it with a good quality oil or alcohol based primer and then top coat with a water based paint. Oil based paints will adhere well to water based paints sp it is unnecessary to prime before top coating, unless you have had to do any repairs to the surface.
In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
Water and oil do not mix. You will need an excellent quality primer specifically designed for this purpose. Answer: A good rule of thumb is never say no to a primer, but once the latex paint has dried, all the water is evaporated out of it. As long as the surface is clean, you can go over latex paint with oil without using a primer. If you do want to use a primer, use an oil based primer prior to topcoat.
There are some water based coatings that will adhere to an oil based surface without using a primer; however, an oil or acrylic-based primer, used as a bridge, will allow you to paint latex over an oil-base paint trouble free.

No, latex paint is water-based, not oil-based.
