Can the word trampoline be used as a possessive noun?
Kind of like, the trampoline's elasticity ?
Or, ...belonged to the trampoline's frame... ?
Got the doubt because my auto-correct (granted, it was the auto-correct in Google Docs) marked the word as wrong
You can turn any noun into a possessive noun (or at least, I can't find any evidence that you can't).
"Trampoline's" is perfectly valid, and it's simply showing up in Google Docs as incorrect because that word isn't in Google's spell check dictionary, as many words aren't.
That said, some people may find it more natural to say "the elasticity of the trampoline" or "the frame of the trampoline." Find what sounds best to you and be consistent.
Many writers consider it bad form to use apostrophe -s possessives with pieces of furniture and buildings or inanimate objects in general. Instead of "the desk's edge" (according to many authorities), we should write "the edge of the desk" and instead of "the hotel's windows" we should write "the windows of the hotel." In fact, we would probably avoid the possessive altogether and use the noun as an attributive: "the hotel windows." This rule (if, in fact, it is one) is no longer universally endorsed. We would not say "the radio of that car" instead of "that car's radio" (or the "car radio") and we would not write "the desire of my heart" instead of "my heart's desire." Writing "the edge of the ski" would probably be an improvement over "the ski's edge," however.

I can see both usages:
"My trampoline's frame is powder coated to prevent corrosion"
"My trampoline frame is powder coated to prevent corrosion"
In general I try to write using possessives only if the possessor acting as an agent, and in some way has ownership. Thus:
"The dog's bed..." is the bed of a particular dog. When it first came into the house it wasn't his,and he sniffed it with suspicion.
"The dog bed..." is pointing out a particular pet bed in the room, but not ascribing possession to it.
