Kindle does not have native Arabic support so you can not read any Arabic text as mobi or text files. But you can always convert your text into pdf or image.
See the related link to download The Qur'an in Arabic.
From hardware and display capability point of view, yes the Quran can be displayed and read on a Kindle screen just like a regular paper print. The format normally used is pdf. The pdf support provided by kindle is limited. But then there are certain copies of Quran available freely on internet that are formatted keeping specifically kindle in mind. The display, font style and font size are optimized for small screen and are very readable on kindle.
Some Muslims may find the act of using a kindle an insult, maybe you should use it else where .While your in the Masjid Al Haram content yourself with reading the copies provided or purchase the Quran. Others may see it as disrespect also, but this is just my opinion, you do not have to take my advise, or you can if you want, but get others opinions before you make the desision. Chose wisely.
