Depends on what you call 'safe'.
If you disable the SSID broadcast, then the chances of finding your wireless connection gets very very slim (but probably not impossible).

But still, if someone happened to remember your SSID, he would still be able to connect to it. And if you don't have other security features enabled (like WPA) they would still be able to use the wireless connection.

So, it is 'safer' to disable the broadcast than if you wouldn't.
But it would be even more 'safe' if you would also enable the WPA encryption.

PS: the model of router doesn't matter for this though. This goes for all routers...
