Strike up and strike a chord share a verb but express different ideas.
In workplace use, people often strike up conversations or relationships. Someone or something strikes a chord when they create a strong feeling or sense of recognition. The phrases do not replace each other in these patterns.
Different subjects, different meanings
With strike up, the subject begins something. Common objects include a conversation, friendship, or partnership. A band can also strike up a tune, so the phrase is not limited to social contact.
With strike a chord, the subject causes a feeling or recognition. It may be a message, story, image, experience, or idea. This phrase does not mean that an interaction began.
The expressions share the verb strike and a short fixed shape. Their usual meanings remain distinct.

"She struck up a conversation with a prospective client at the trade show" describes an interaction beginning. "She struck a chord with a prospective client at the trade show" makes a different claim. It says that she created a strong response, not that a conversation began.
"The keynote struck a chord with the audience, and dozens of attendees mentioned it afterward" describes a strong response. The keynote did not begin an interaction, so strike up would not express that idea.
"His story about the failed product launch struck a chord with the room, and afterward three people came up and struck up conversations with him about it" uses both expressions. The story creates a response. The people then begin separate conversations.
