It would be highly unusual and likely confusing unless you are speaking with a botanist or in an academic setting. Use 'small leaf' or 'tiny leaf' instead.
The opposite is a 'megaphyll', which is the type of leaf found in ferns, gymnosperms, and angiosperms, characterized by a complex, branched vascular system.
