Can you see light on one side and dark on the other as if your seeing night and day

This happens everywhere in the world twice a day. It is called "morning" or "nightfall". There is nothing special about the Greenwich Time line, as this is an imaginary, man-made, line that does not really exist.

There would be nothing special about what you see in and around the Greenwich time line (or the international date line). There is daylight, night time and twilight. Twilight is what happens as we switch from daylight to night time or night time to daylight. It is a fairly gradual change so you would not see an abrupt change from light to dark.
Every time I have flown in a plane during twilight, I have not been high enough to see enough of the earth to see both day and night at the same time. I think you would have to be in a spaceship to see what you are talking about (and it wouldn't matter if you were near the Greenwich time line).

The edge of light and dark you refer to is called the terminator. On Earth, the terminator has a very broad gradient due to the light scattering from the atmosphere. In order to observe this gradient in such a way that it is apparant, you have to be fairly high off the ground. Passengers on the old Concorde SST (which cruised at an altitude around 60,000 feet, much higher than most jet liners) reported seeing the Earth's terminator when crossing it, as well as being able to see the curvature of the horizon quite well.

there's nothing particular about the greenwich time line as far as night/day goes.
if you happened to be flying overhead right at sunrise or sunset, you could see a line of light/darkness moving across the ground, but that is true anywhere in the world, since as the earth spins on it's axis, it's always sunrise along some line, and sunset on another line on the opposite side of the earth.

I do not know if you can see light on one side then dark on the other...but here is a web site to check out.
