Is there a word or phrase for when you break a word in a different place to give a different meaning?

Psycholinguist Gary Libben coined a term for these kind of compounds: ambiguous novel compound.

Ambiguous novel compounds are strings such as clamprod which have two possible parses (in this case clam-prod and clamp-rod).

It is not a well-established term yet but it seems like it is an accepted term in morphological studies. There are several publications using Libben's term and mentioning his experiments regarding morphological parsing.

One of the publications is "The Oxford Handbook of Derivational Morphology" edited by Rochelle Lieber, Pavol Štekaue and below is an excerpt about ambiguous novel compounds from the book:

A 2003 article by Eric Shackle (to which I contributed some examples) referred to words that can be broken into two smaller unrelated words as hyp-hens. It noted that prior to widespread use of computer word processors, newspapers often broke words over a line at an inappropriate point, sometimes generating two new words that on occasion bring about an amusing change in the meaning of the sentence.

Here are some more examples of so-called hyp-hens in English:
