Boot the ISO directly from GRUB as described here

[HowTo] Booting manjaro iso directly with grub

Difficulty: ★☆☆☆☆ We are all familiar with burning live usb stick to boot our Manjaro isos. That is useful when you are installing manjaro on a new machine. However, if you already have linux installed with grub, there is a better way to boot Manjaro iso files. I usually do this when I test new iso files for a new release or when I need to use a rescue system because one of my experiments rendered my installation unbootable. You can boot the .iso file directly from your hard drive without burn…

Thanks I understood , but is it risky?

Do you count wiping out your fedora installation a risk? That is the whole purpose of this operation, no? You WILL lose all your previous data on the fedora installation, so I suggest backing it up.

If your manjaro installation fails after you have formatted your hard drive, then you will be left without a bootable system. So you only get one shot at this. This risk can be avoided by having a separate /boot partition, where both the grub configuration and the iso file are stored. Then you can just reboot the iso if things don’t succeed the first time. I would still recommend having a live usb stick just in case.

So, booting the iso from grub is risk free, but reinstalling over the partition where the booted iso is stored can be risky. At least you can test manjaro from the live iso without issues.
