Would it be acceptable to say something like this "For a translation sample, please see the article XY on website XY" that was translated by me?
Yes, I don't think you're endangering anyone's confidentiality by claiming that you are the translator of a publicly available text.
Is it okay to say that you've translated it for an agency, or would that reflect badly on me?
It won't reflect poorly on you if you admit to that, but the specific identity of the agency is part of the confidential information (unless it is revealed somewhere public).
