Ultimately depends on the system you are on. If you are on Ubuntu, for example, I believe you could use the included "Startup Disk Creator."
I also believe it could not be ran from any computer. First off, it needs the ability to boot from USB devices. Secondly, its hardware needs to be supported by Trisquel.
EDIT: my bad. I thought you meant running from an USB stick. Please ignore most of this post, then. :/
