Not really. That's like saying that all lamps over 300 watts are to be called lamps and those less than 300 watts are to be called light bulbs. A difference between control voltage and switching voltage isn't really a discriminator either.
Is the "condenser" in the ignition of your pre-1980s car not a capacitor, just because the auto mechanic calls it by that name?
There is a difference. Contactors are usually used when driving motors. They have a higher voltage rating to prevent arc-over when stopping a motor. Relays are often used in control circuits and have lower voltage ratings. N.B. There is a voltage rating for the coil that pulls-in the contacts, and a different voltage / current rating for the contacts that drive the load..

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
