Only if you use the length to double the number of strands.

The answer is implicit in the famous saying, "A chain is only as strong as its weakest link."
Similarly, a rope is only as strong as any one section of the rope, so making it longer doesn't make it stronger. But it stays equally strong, so long as each section of the rope is equally strong. (If one section is weaker .... well, then read the quote above.)
But keep in mind that when something is supported by a rope, the rope may have to support ITS OWN weight, as well as that of the object. In this case, the longer rope results in more weight being supported by the rope, so it is under more strain and more likely to break. It's not that the rope is weaker, but it is subject to more strain if it is longer and has to support its own weight.
Interesting observation:
If you think about it, you could make a rope so long that it couldn't even support its own weight. If you could build a tower 100 miles tall and hang a 100-mile-long rope from it, the weight of the rope would likely be enough to cause the rope to break. And it wouldn't help to make the rope twice as thick, because that would simply make it twice as strong and twice as heavy, so the increased weight would exactly offset the increased strength, and it would still break. The only way it would not break is if you used a different, stronger material that could hold 100 miles of its own weight.

Between a long rope and short rope of the same thickness,same material etc, the short rope is stronger.

No a long rope isn't stronger than a short rope.

No, it would be equally strong in tensile strength.
Are you worried about it breaking? In the real world there is more length, so more possibilities for it to fail. The rope factory has a better chance to make one foot of adequate rope than one hundred feet in a row. Like that.
