Hardly.
You can install Linux-Libre in any distro, Ubuntu for example. That would
still leave you with the proprietary junk you had there before.
As for the machine itself, you still have the BIOS (only a few machines
support Libreboot) and possibly more hardware components that run proprietary
software.
This is not to demotivate you. Each baby step counts. Install linux libre, or
switch to Trisquel altogether. Don't install proprietary software yourself.
When possible, buy hardware compatible with free software elements (printers,
laptops etc) and each baby step will take you closer to freedom. Keep up the
faith!
