In my experience, publishers don't bother to fiddle with word wrap issues except in connection with coverlines and other display type (headlines, subheads, table titles, and sometimes captions).
Part of the reason for their restraint on this score is that they've elected to dedicate their limited editorial resources to more-pressing problems (such as narrative coherence and typographical accuracy) instead. But a further issue is that artificially arranging to keep ideas together on a line can have a detrimental effect on the jaggedness of a paragraph's right margin (if the text is set ragged right) or on the looseness of particular lines (if the text is set right-justified).
In other words, keeping ideas together on a line isn't necessarily a cost-free process.
In display type, however, the benefits of keeping blocks of text together to avoid ending lines with weak words such as "a," "the," or "and," and to avoid inviting misinterpretations of the type Kris mentions in a comment above increase, while the disadvantages tend to diminish—especially since coverlines (in particular) are subject to painstaking alteration to fit available space more effectively.
In the case of a report that you type, format, and publish yourself, of course, you are free to be as meticulous as you wish within the limits of the time available. But I'm not aware of any widely enforced rules in major style guides governing the question of how to handle line turnovers.
