Restoring Time Machine backup made on a previous OS X version

My macbook pro, running OS X Lion (10.7.5) got stolen last night. Luckily they didn't take my external drive, where I have a Time Machine back up of all my data, which is extremely important to me (mostly, unfinished music productions projects in Ableton)

Since new MacBooks ship with OS X Yosemite, would I able to restore my Time Machine backup on a new laptop?
