Have a look at this video, if the pram that you're looking at has this type of adapter, that is the type of adapter that Cybex uses.
In the video Margaret states that you still have to look at the compatability lists. Personally, I feel that it is not strictly necessary for them to be on either list. The reason for this is that car seat and pushchair companies cannot possibly keep up to date with every single model. The car seat companies tend to test their seats with the most popular models of pushchair (which will be a limited selection) and the pushchair companies tend to have a stock of the most popular models of car seat and test these, but car seat companies, especially Cybex, are often releasing new models year after year with only very slight tweaks. So the pushchair company might have the model from 4/5 years ago but not the latest one. And if you choose a pushchair that was released before the car seat you're looking at, then it won't be on the list for that reason.
But for example, Cybex Cloud T is not hugely different than Cybex Cloud Z or Q, which are the older versions, so more likely to appear on compatability lists. In fact, it's lighter. But the part where the pram attachments go in is very likely to be totally unchanged from the previous models in the same series.
As shown in the video, the adapters can all be slightly different so there will be occasional situations where a specific model won't click in, also the angle of the adapters to the car seat and the position of it on the buggy frame will differ. So there are individual cases where it won't work. And if you want to be 100% sure, then the compatibility lists are a good idea to check.
But for example if it says Maxi Cosi Pebble Plus and you have Maxi Cosi Pebble Pro, they are the same shell so this will never be an issue. And you can broadly make the assumption that most of the time if the name is the same like this that they are close enough that it will work. Doubly so if you look at pictures and can see they are the same shape.
