It could be ! I've seen poems where the words don't always rhyme in any rhythm but usually do later in the paragraph. So, there must be some things to rhyme in a poem but not necessarily all the words all the time. A few words still makes it a poem.
Are rhyming words important in poem? If there are no rhyming words or little - is it still called a poem?
Poetry uses all sorts of rhythmic qualities of language to evoke emotion, to tell a story, whatever...! No poem has to rhyme in any way, but I suppose what differentiates a poem (more specifically, a narrative poem) from a story is mostly format and SOME sort of rhythm, be it through diction, meter, sounds, stanzas, its visual presentation, etc. To avoid confusion, I'd assume that would be the reason for so many different and specific forms of poetry (such as haikus, sonnets, ballads...) or even some genres (such as epics, satirical, prose...)
My point is rhyme doesn't have to be an important factor when writing a poem. If anything, it's the most common attribute when analyzing, reading, or writing poetry. "Poetry" is as subjective as it gets, but there are elements that distinguish them from any other form of literature.
