Is it possible to record a trademark if the name of the trademark consists only of two characters?

Yes, any mark with at least one character is acceptable in the Clearinghouse. Please note however that all two-character labels will be withheld from registration or allocated to Registry Operator at the second level within the TLD in order to avoid confusion with country codes. Such labels may not be activated, and may not be released for registration to any person or entity other than Registry Operator, unless the Registry Operator reaches agreement with the related government and country-code manager of the string. The Registry Operator may also propose the release of these reservations based on its implementation of measures to avoid confusion with the corresponding country codes, subject to approval by ICANN.
