I don't think that the first version can be optimized to the same code in this case - it needs to add or subtract based on the condition whilst the second always adds. In fact the code size for the first is 40, for the second 24, FWIW here's the CIL:

.method private hidebysig static void  TestA() cil managed
{
  // Code size       40 (0x28)
  .maxstack  2
  .locals init ([0] bool CS$4$0000)
  IL_0000:  nop
  IL_0001:  ldsfld     bool ConsoleApplication2.Program::Checked
  IL_0006:  ldc.i4.0
  IL_0007:  ceq
  IL_0009:  stloc.0
  IL_000a:  ldloc.0
  IL_000b:  brtrue.s   IL_001b
  IL_000d:  ldsfld     int32 ConsoleApplication2.Program::_CheckItemsCount
  IL_0012:  ldc.i4.1
  IL_0013:  add
  IL_0014:  stsfld     int32 ConsoleApplication2.Program::_CheckItemsCount
  IL_0019:  br.s       IL_0027
  IL_001b:  ldsfld     int32 ConsoleApplication2.Program::_CheckItemsCount
  IL_0020:  ldc.i4.1
  IL_0021:  sub
  IL_0022:  stsfld     int32 ConsoleApplication2.Program::_CheckItemsCount
  IL_0027:  ret
} // end of method Program::TestA

v

.method private hidebysig static void  TestB() cil managed
{
  // Code size       24 (0x18)
  .maxstack  8
  IL_0000:  nop
  IL_0001:  ldsfld     int32 ConsoleApplication2.Program::_CheckItemsCount
  IL_0006:  ldsfld     bool ConsoleApplication2.Program::Checked
