No. Only a black hole has an event horizon.
A black hole has an event horizon, beyond which nothing can escape, including light. Neutron stars also have an event horizon, called the "surface" or "crust," which marks the boundary within which matter is crushed by extreme gravity. White dwarfs, being less massive, do not have an event horizon.

A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
The "boundary" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.

A white dwarf cooking into a black dwarf
The upper limit to the mass of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. Beyond this point, the white dwarf may collapse and explode in a supernova event.
No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.
If a white dwarf gained enough mass to reach the 1.4 solar-mass white dwarf limit, it would undergo a catastrophic event known as a Type Ia supernova. This explosion would release a tremendous amount of energy and result in the complete destruction of the white dwarf.
Event Horizon was released on 08/15/1997.
The Production Budget for Event Horizon was $60,000,000.
A white hole is a theoretical gap in space-time where matter and energy are ejected by its event horizon.
The duration of Event Horizon - film - is 1.58 hours.
A nova event occurs when a white dwarf in a binary system accepts material from a nearby companion star, causing a runaway nuclear fusion explosion on the surface of the white dwarf. This explosion results in a sudden increase in brightness that can last for several days to a few weeks.
Event Horizon - film - was created on 1997-08-15.
Event Horizon grossed $26,673,242 worldwide.
