Sure. You can think of a blockchain as providing database-like structures. The only difference is that you don't have to decide who holds that database, so you sidestep the governance issue of who's going to hold that data.
It also has very strong technical properties in terms of what data can be written. The data that's written will be validated according to sets of rules you can write, and you can write these in software or code. To the extent that you could think of a computer being able to record or act on this information, then a blockchain could be dropped in to provide that same functionality. It could be done in a way that you don't have to pick one person to be in charge of running that database.
It is a relevant technology. There are a lot of open questions and research questions before you can just drop one in.
