Your question is similar to https://community.notepad-plus-plus.org/topic/11908/bookmarking-lines-containing-values-in-other-file and https://community.notepad-plus-plus.org/topic/20052/search-and-replace-between-2-files …
Can you learn from those questions and figure out how to adapt those solutions to delete from your target file? (For example, in the “bookmarking” example, after “bookmarking” in the target file, you could delete the bookmarked lines using Search > Bookmark > Remove Bookmarked Lines; or with the search-and-replace, instead of replacing with some actual value, you could replace-with-empty, which is effectively deleting)
I thought there were others, too; at some point in the past, I remember this being solved with PythonScript, but I haven’t found it yet.

It’s still not the one with a PythonScript solution, but I found “Use Text File to Remove Lines” which I believe is exactly what you want to do. Pay attention to the caveats between the solutions given by @guy038 in that discussion and the ones from me – they each have their pros and cons.

Here’s one that is very similar to this current question:
A posting in that thread links to a PythonScript solution here:
