I'd say yes, but.... BR are designed for more temperature tolerance than CR batteries. If the battery is helping store calibration data, I'd make sure to some how wire up some 3V power in parallel to the battery so that you don't lose data when it is removed.

http://www.panasonic.com/industrial/batteries-oem/oem/primary-coin-cylindrical/br-cr.aspxCoin type lithium batteries are high energy, high reliability batteries for a variety of applications. The 3 volts in these high energy density batteries is about twice that of conventional dry batteries.
Panasonic coin type lithium batteries are available in two types: poly-carbonmonofluoride lithium batteries (BR series) for uses that require extended reliability and safety over a broad temperature range and manganese dioxide lithium batteries (CR series) for uses that require and strong load pulse characteristics.
The CR Lithium primary coin cells contain Perchlorate over the limit specified by the state legislature of California and are therefore subject to requirements in the California Code of Regulations, title 22, division 4.5: Chapter 33 – Best Management Practices for Perchlorate Materials.
•Very safe (poly-carbonmonofluoride lithium) <------------
•Extremely strong load pulse characteristics (manganese dioxide lithium)
•Operating temperature range:
•BR Coin Cells: -30ºC ~ +80ºC <------------
•CR Coin Cells: -30ºC ~ +60ºC
To be safe, probably should stick with the BR battery, you don't want it popping and ruining your nice gear.
