Not really. Ancient authors had to be much more conscious than we do of how much space they were consuming. Paper (papyrus or parchment) was much more expensive, and scrolls were difficult to work with once they get beyond a certain size.
The 3rd century B.C. Greek poet Callimachus famously said, "A large scroll is a large evil."
Luke's Gospel is already the longest book of the New Testament, and this forced him to omit material he might otherwise have included.
He had tons of special material not yet recorded in Gospel form that he wanted to put down (e.g., his Infancy Narrative), and he knew that the Feeding of the Four Thousand was already recorded in one of the other Gospels (Matthew or Mark, depending on which you think he used in composing his).
Also, The Feeding of the Four Thousand occurs in a part of Mark that is referred to as "the Great Omission" (from around Mark 6:47 to around Mark 8:27). It's a whole block of text that Luke basically leapt over--if he was using Mark--likely for space-saving reasons.
