Yes, if the machine is on a LAN you can VPN into the network and if the network adapter (of the sleeping machine) supports Wake On Lan you can send a "magic packet" to the adapter and wake up the computer. Most network adapters support WOL.

What do you mean by _Wake On Lan_? Do you mean I can only do that
thing for a pc in the same subnet?


This covers the basics.

Look for another article, that addresses port forwarding
of whatever port is necessary, to make Wake On LAN work.
One example of an article, here.

If your computer is sleeping in S3 Suspend To RAM, this
might work quite nicely. But if the power goes off while
you're away, you could lose touch with the computer (the
LAN chip may not be set up right when power is restored).
Similarly, if the power on your router is cycled, it
may not be in a state to talk to the high speed modem
or whatever. The setup is inherently unreliable, for
operation for long periods of time, while you're a long
distance from the equipment. If you were using this
while you were at work in the same city, then it would
be an easy drive, to go home and fix your setup. If
you're half way around the world, and WOL doesn't work
for some reason, it is going to be harder to fix.
A lot of component parts of this operation, all have
to work properly, which is why I don't rate it as a
reliable method.

Whether an item like the following might help you, is
debatable. It depends on whether your Internet connection
is reliable enough, such that once the computer is
turned on, the computer will be reachable from the
Internet. So even with a telephone remote, it might
still be difficult to reach the computer over the
Internet. You need an Internet setup that restores
itself after a power failure.
