Many people say no, however it will most likely be a cheap update as it is only a slight feature update.
Mac OS X 10.7 (Lion) was created by a team of programmers at Apple.
You have Leopard which is (10.5.8). One of the requirements for installing Lion is that you already have Snow Leopard (OSx 10.6) or later installed. The main reason is that Lion is available only via the Mac App Store, and the Mac App Store debuted in Mac OSx Snow Leopard (10.6.6). In other words, you need Snow Leopard just to purchase and download Lion. So you are going to have to purchase and install Snow Leopard before you can proceed to purchase and install Lion. If you bought your Mac at a retail store then go back and ask them for a free updrade to Snow Leopard. They may just give it to you for free if you agree to purchase Lion which should cost you around $20. Does not hurt to ask. If you purchased it online then contact Apple for the upgrade to Snow Leopard.
Mac "Lion" and Mac "Snow Leopard" refer to iterations of Apple's Mac OS X (operating system, version 10). "Lion" is the newest as of this writing, and is version 10.7, while "Snow Leopard" is its immediate predecessor, and is version 10.6.
