no. see here:
http://msdn.microsoft.com/en-us/library/ms190273.aspx
reason:
Both the source table or partition, and the target table or partition, must reside in the same filegroup.
this restriction is logical, btw, as this statement will do nothing but change the points, it will NOT move actually any data.

You can't move data between tables (let alone databases) using an ALTER TABLE statement like that. To move that data, you'd have to do an old-fashioned INSERT followed by a DELETE. Or, to do it in a single statement, you could try this:
This will delete the rows from TableA and put them in TableB in a single, atomic transaction. If any part of the insert/delete fails, it will roll the whole thing back and leave the rows where they started.
DELETE DatabaseA.TableA
OUTPUT deleted.*
INTO DatabaseB.TableB
This will delete the rows from TableA and put them in TableB in a single, atomic transaction. If any part of the insert/delete fails, it will roll the whole thing back and leave the rows where they started.
