Not really. MTBF means "it'll run for 10 minutes without falling over". SLA can mean anything. If I was an office manager, I might well say (indeed, it's pretty much our internal SLA) that our systems will be guaranteed available between 8am and 6pm. So I can have 14 hours downtime a day, and still meet my "100% availability" guarantee to my end users :-)
Doesn't quite work that way of course :-) with offices in New York and Hong Kong, that "available between 8 and 6" guarantee means that I only have a few hours when I can take the system out ... :-) But basically, all an SLA is, is a statement that service will be available within certain (acceptable to both sides) constraints. Whether time when it's available, or possibly response times (eg we can't run heavy maintenance tasks at certain times because the users will curse us etc etc).
