Mediumly long answer, yes (ish) but it's ugly and you probably wouldn't want to do it.

please note: this code creates a physical table

CREATE TABLE MyTest (a int, b int, d int, e int)

INSERT INTO MyTest (a,b,d,e) VALUES(1,2,4,5)

SELECT * FROM MyTest

ALTER TABLE MyTest ADD c int
ALTER TABLE MyTest ADD d_new int
ALTER TABLE MyTest ADD e_new int

UPDATE MyTest SET d_new = d, e_new = e

ALTER TABLE MyTest DROP COLUMN d
ALTER TABLE MyTest DROP COLUMN e

EXEC SP_RENAME 'MyTest.d_new', 'd';
EXEC SP_RENAME 'MyTest.e_new', 'e';

SELECT * FROM MyTest 

DROP TABLE MyTest
