Nope. Although the Quran is very well preserved for such an old document, there are multiple variants. Muslims often claim it's perfectly preserved, but it's just not. See for example: https://www.youtube.com/watch?v=aYwwX5lc_ww (start 8 minutes in).
If you want to dive in further here is a video that address the issue of what you linked : https://youtu.be/eTz96M1AkVo?t=400 There are many such online.
At the end of the day there is only one Quran with 114 chapters it's start with surat Al-Fatiha and ends with the last surat An-Nas.

Finally, I want to invite you to become a muslim. Meaning, I invite you to submit your will to the one and only creator the same one who sent Moses, Jesus and Mohammed (Peace be upon them all) so that you may attain eternal paradise and avoid hell. In the end you make your choice and I'm only here as a conveyor of the message.
There are different versions of the sources, as well as different trabslations; most recent versions of the Bible are based on some scholarship which incorporates and makes some effort to reconcile the differences, rather than simply choosing one set as authoritative, but the differences in the sources contribute to difference between translations.
Look how many version of the bibles there is. However, there is only one Quran. 114 chapters. It always start with surat Al-Fatiha and ends with surat Al-Anas.
The Quran is memorized by millions of muslims word by word. There is even a quran in a museum in the UK, Birmigham where it was carbon dated around the time of the Prophet Muhammad (Peace be upon him). This demonstrate that the quran is preserved.
Moses and Jesus and all the previous prophets are muslims. In the sense that muslims means someone who submits his will to the one creator. However, as throught history it always devolved into polytheism. Look at christianity with the concept of the trinity. Islam is so simple and make so much more sense just worship one creator. He is not a man, not a woman doesn't have children, He is above all of this.
I would suggest looking at this video : What is the difference between the Quran & the Bible? | Great Explanation | Sh. Uthman Ibn Farooq : https://www.youtube.com/watch?v=q0WSzqnJzRo
