No.

SQL Server doesn't keep COUNT(*) in metadata like MyISAM, it calculates it every time.

UPDATE: If you need an estimate, you can use statistics metadata:

SELECT  rows
FROM    dbo.sysindexes
WHERE   name = @primary_key,

where @primary_key is your table's primary key name.

This will return the COUNT(*) from last statistics update.
