As karel's answer says, yes, you just burn the iso to a USB drive (e.g. dd if=./image.iso of=/dev/sdb) and go through the installer.

As for other knowledge I have relating to this, mostly from my own experimentation with an unsupported device, I'll dump that here, as you may find it helpful.

As for devices that aren't officially supported:

Because 25.04 now uses stubble, it's more difficult to use unsupported devices. On 24.10, if you grab an devicetree blob from somewhere else (e.g. a postmarketOS kernel), you can put it in the /casper/dtbs folder and modify boot/grub/grub.cfg. You'll want to modify/add regex for the $system_product_version of whatever you're using, and specify the devicetree (dtb="devicetree /casper/dtbs/x1p42100-asus-zenbook-a14.dtb") - look at the other devices listed there for examples.

You can make your own modifiable live image by, instead of burning the iso file to your disk, creating a new GPT partition table and a FAT32 partition, then copying all the iso's files to that new FAT32 partition. However, this will fail to install - I believe this is due to apt breaking because FAT32 does not support symbolic links.
