s it really possible to cover untested code?
And to cover years of code that is untested which also means it was not designed to be testable and therefore is tough to test?

I'd go with the Scouts mentality of leaving code better than you found it. Add tests when you're touching a piece of code, so you can already edit it to be more testable. Yes that might be a slightly risky refactor because it's not covered by tests, but then again, it's no more risky than the development you did before TDD.
