Its highly unlikely and the answer is going to have to be a no.

EDIT
Yes a level 15 can defeat elvarg, though it would not be easy, and I am not sure you are actually capable of reaching him at level 15 due to quest requirements..
The combat level is a rather poor indicator of a characters actual fighting ability.
For example, a player could only train melee until attack, strength, and defense were level 60. This would put said players level at around 50-60. If the same player decided to start training ranged, even though his combat level would be high, he would not be a powerfull ranger due to him having very low ranged levels, where as a player who just trains ranged and def could have 45 ranged/def/hp and be a lower level, yet have a easier time on elvarg. It would most likely be easier due to elvargs weakness to ranged attacks.
If you have an inventory full of lobsters, an anti-dragonfire shield, an amulet of power, and a rune longsword set on lunge, you will send her packing (An amulet of power, and a rune longsword set on lunge are optional but preferred.)
elvarg is lvl. 83 in runescape.... seriosly
pick the 3 one
assuming you are talking about elvarg...the dragon from the runescape quest ''dragon slayer''.....its rather easy and if u have the skill you can beat it with a lv3.....i myself was around lv50 when i defeated it with melee.....elvarg is perhaps the easiest dragon to kill in runescape...bring food and an anti-dragon shield....hope this helped
Providing you have brought and anti-dragon shield that you must obtain as part of the quest, then a level 71 should have no bother killing Elvarg if they bring decent food.
No, because there is no double battle in the elite four

Yes, you can wear rune and fight green dragons. I'm guessing this question is pertaining to Elvarg more than just regular green dragons. If that's the case, you can still fight Elvarg while wearing rune, you just can't wear the rune plate as you have to defeat Elvarg in order to wear it after returning to the Hero's Guild for your reward.
on sapphire or ruby, get a level 57 swampert, get a level 48 seviper, a level 43 tropiuos, a level 50 mawile/sableye, level 45 hariama and level 52 kyogre/groudon and this is certain sucsess or you have cruddy moves or you have a glitch in your game
the only dragon on a f2p server is "Elvarg" who is fought in the Dragon Slayer quest. Unfortunatley, Elvarg doensn't allow a rematch.
