Welcome to the Q&A Forum

Have you heard the PT Barnum quote, "I don't care what you say about me, just spell my name right."? That's going to be a factor here. While the obvious ideal is to get a link from the article, as you mentioned it may not be appropriate and the client may not be comfortable with those types of requests. If the name is fairly unique, eg "Meiers and Young, LLP", then it's likely that Google can make an association over time using concepts like co-occurence. While that's not likely to be as strong as a link, it does likely provide some value in sending those citation signals to Google. To make better use of that press, I would typically add a page such as www.client.com/press/ or www.client.com/in-the-news/ that lists those press mentions in reverse chronological order, and feel free to link directly to them if you think it actually provides value to potential clients viewing your site.
